Lcm of 2 and 3 is 6. now make sure your denominators are same 2/6 and 3/6. Need 3 rational no. so multiply the numerator and denominator both by 4. (for eg 5 rational no means by 6....ie). Now u will get 8/24 and http://www.12/24.in between 3 required rational no are there... 9/24'10/24,11/24.

Karthik Vendhan K replied | 17/11/2016

1/3 = 0.33333.... and 1/2 = 0.5
Rational numbers between 0.3333..... and 0.5 were 0.34 = 34/100 = 17/50 , 0.35 = 35/100 = 7/20, 0.36 = 36/100 = 9/25, ..................,0.4 = 40 /100 = 2/5, etc.
There are infinite rational numbers between any two rational numbers.

Find the length of the tangent from a point which is at a distance of 5 cm from the centre of the circle of radius 3 cm?

Tanay replied | 05/12/2016

So, if you draw a circle it will form a right angle triangle with hypotenuse 5 cm and base 3 cm. using Pythagoras theorem, the length will be equal to 4 cm.
