Firstly we need to define recurring decimal as a rational number that does not terminate.

Example 1, 0.444444444...

Example 2, 0.123123123...

A fraction is a number in which the numerator is divided by the denominator. In terminating decimals, the number of decimal places determines if the denominator would be 10, 100 or 1000 for fractions of tenths, hundredths and thousandths respectively.

Recurring decimals are patterned and can be simplified with algebra.

Using Example 1, only 1 digit is repeated

Let x = 0.4444444444...

10x = 4.4444444444...

Then 10x - x = 4.4444444444... - 0.4444444444...

9x = 4

x = 4/9

Example 2

Let x = 0.123123123...

10x = 1.231231231...

*which complicate things, we are looking to eliminate all decimal points when we subtract x from this

100x = 12.312312312...

*this does not help either, 3 digits are repeated, so we try

1000x = 123.123123123...

- x = 0.123123123...

So we have 999x = 123

Therefore x = 123/999

How to convert a decimal into percentage?

We will follow the below following steps for converting a decimal into a percentage:**Step I:** Obtain the number in decimal form.**Step II:** Multiply the number in decimal form by 100 and put percent sign (%)**Note:** When we multiply the decimal number by 100, then we need to shift the decimal point two places to the right (add zeros if necessary).**I. Express each of the following decimal as percent:**

(i) 0.8 = 0.8 × 100 % = 80 %

(ii) 1.2 = 1.2 × 100 % = 120 %

(iii) 7.1 = 7.1 × 100 % = 710 %

(iv) 10.1 = 10.1 × 100 % = 1010 %

(v) 31.3 = 31.3 × 100 % = 3130 %

(vi) 123.7 = 123.7 × 100 % = 12370 %

(vii) 101.9 = 101.9 × 100 % = 10190 %**II. Conversion of decimal into percent:**

(i) 0.29 = 0.29 × 100 % = 29 %

(ii) 0.25 = 0.25 × 100 % = 25 %

(iii) 0.01 = 0.01 × 100 % = 1 %

(iv) 0.51 = 0.51 × 100 % = 51 %

(v) 13.01 = 13.01 × 100 % = 1301 %

(vi) 201.17 = 201.17 × 100 % = 20117 %

(vii) 100.11 = 100.11 × 100 % = 10011 %**III. Convert the following decimal into a percentage:**

(i) 0.083 = 0.083 × 100 % = 8.3 %

(ii) 0.225 = 0.225 × 100 % = 22.5 %

(iii) 0.001 = 0.001 × 100 % = 0.1 %

(iv) 0.003 = 0.003 × 100% = 0.3 %

(v) 0.107 = 0.107 × 100 % = 10.7 %

(vi) 1.037 = 1.037 × 100 % = 103.7 %

(vii) 21.275 = 21.275 × 100 % = 2127.5 %

Dear all we know that sentence is the base of any language. Before learning about the sentence. I ask you to have a look at things surrounding you now. For instance, if you are at home, you will be sitting in a chair, and things were surrounding you will be television, table, laptop, curtain, fan, air conditioner etc. At any point, if in case you are not sure about the alternate words of the things you said in English from your mother tongue. It means most of the words we use in our day to day life are from the English Language. Then why we are not confident in speaking the English language? Its purely we don't know how to group the words to form a sentence.

The sentence is nothing but the group of words which gives a complete meaning. Every sentence in English has a combination of subject and verb.

Sentence pattern : subject + verb + predicate

Subject: Name of a person, thing or place

Verb: used to define the action

Predicate: something which is done to the subject

Example: The boy stood on the table

Boy: subject

Stood: verb

On the table: predicate

Thanks, for reading, ping me for further doubts

Example: I. Find least common multiple (LCM) of 21 and 48. Solution Step 1: The prime factors of 21 and 48 are 21 = 3 × 7 48 = 2 × 2 × 2 × 2 × 3 Step 2: Maximum occurrences of the prime factors are 2 (4 times); 3 (1 time); 7 (1 time) Step 3: Least common multiple... read more

Example:

I. Find least common multiple (LCM) of 21 and 48.

Solution

Step 1:

The prime factors of 21 and 48 are 21 = 3 × 7

48 = 2 × 2 × 2 × 2 × 3

Step 2:

Maximum occurrences of the prime factors are 2 (4 times); 3 (1 time); 7 (1 time)

Step 3:

Least common multiple of 21 and 48 = 2 × 2 × 2 × 2 × 3 × 7 = 336

II. Problem 1:

A bell rings every 18 seconds, another every 60 seconds. At 5.00 pm the two ring simultaneously. At what time will the bells ring again at the same time?

Step 1:

A bell rings every 18 seconds, another every 60 seconds

Prime factorizations of 18 and 60 are

18 = 2 × 3 × 3

60 = 2 × 2 × 3 × 5

Step 2:

LCM is the product of maximum occurrences of each prime factor in the given numbers.

Step 3:

So L C M (12, 18) = 2 × 2 × 3 × 3 × 5 = 180seconds = 180/60 = 3 minutes.

So the bells will ring at same time again at 5.03pm

III. Problem 2:

A salesman goes to New York every 15 days for one day and another every 24 days, also for one day. Today, both are in New York. After how many days both salesman will be again in New York on same day?

Step 1:

A salesman goes to New York every 15 days and another every 24 days

Prime factorizations of 15 and 24 are

15 = 3 × 5

24 = 2 × 2 × 2 × 3

Step 2:

LCM is the product of maximum occurrences of each prime factor in the given numbers.

Step 3:

So L C M (12, 18) = 2 × 2 × 2 × 3 × 5 = 120days.

So both salesmen will be in New York after 120 days.

Problem 3:

What is the smallest number that when divided separately by 20 and 48, gives the remainder of 7 every time?

Step 1:

Prime factorizations of 20 and 48 are

20 = 2 × 2 × 5

48 = 2 × 2 × 2 × 2 × 3

Step 2:

LCM is the product of maximum occurrences of each prime factor in the given numbers.

Step 3:

So L C M (20, 48) = 2 × 2 × 2 × 2 × 3 × 5 = 240

The required number is 240 + 7 = 247.

For instance, you refer to drinks as a glass of wine, a half quart of brew, some tea, a pot of espresso and so on. It is smarter to learn in expressions rather than standalone words such as wine, brew, tea etc. You can likewise profit by learning words that are connected.

This approach is practiced by tallied experts across the world, who have mastered the skills to help others speak English in merely 30 days.

Tune in to the video once and read the subtitles to acquire a handle of the substance and stream. Impersonate the storyteller (imitate words) sentence by sentence. Play. Tune in. Delay. Talk. Record (discretionary).Try to speak words as similar as you can. If you record your training, you can think about yours and the original. Or simply tune in to your own sound and be a good spectator of the differences. Repeat this progression until the finish of the video.

3. Think in English: Yes, it’s a must.

You must guide your mind to process information in English rather than your native language. Once you reach a particular level, your mind would not require translation. A suggestive method to instigate re-examining is to keep a journal where you express your everyday ideas and thoughts in English. It doesn’t need to be immaculate or perfect; it is more about getting your view out and thoughts in English with least effort.

4. Public Speaking Events: Participate in it Enormous colleges, theatres and cultural social orders plan out the occasions such as open discussions, reading words and storytelling get-togethers. These are places where you can come and blend with similarly invested individuals and work on your English communication skills. Numerous urban communities are presently facilitating TED or TEDx talks where you can register to take an interest and offer your imaginative thoughts. Check the occasions’ page of your neighborhood college to see whether they are accessible. It may be a harrowing experience, yet an overwhelming learning curve for you!
