To find the multiples of a number, you multiply that number by integers. Let's find the first three multiples of 11:

1. 11×1=1111×1=11
2. 11×2=2211×2=22
3. 11×3=3311×3=33

So, the first three multiples of 11 are 11, 22, and 33.

1. Gather Materials: You'll need a ruler and a blank sheet of paper.

2. Mark Starting Point: Place the ruler horizontally on the paper. Use a pencil to make a small mark at the starting point of the line segment.

3. Measure and Mark Length: Starting from the mark you made, use the ruler to measure 7.3 cm along the paper. Make another small mark at this point.

4. Draw Line: Connect the two marks using a straight line drawn with your pencil. Ensure that your line is straight and extends from the starting point to the end point.

5. Check Length: Measure the line segment you've drawn using the ruler to verify that it is indeed 7.3 cm long.

By following these steps carefully, you can draw a line segment of length 7.3 cm accurately using a ruler and a pencil.

To construct a line segment of length 5.6 cm using a ruler and compasses, follow these steps:

1. Gather Materials: You'll need a ruler, compass, pencil, and a blank sheet of paper.

2. Draw a Straight Line: Use the ruler and pencil to draw a straight line. This will serve as the base for your construction.

3. Mark the Starting Point: Choose a point on the line to serve as the starting point of your line segment. Label it as point A.

4. Draw an Arc: With the compass, draw an arc above the line segment from point A. Adjust the compass width to approximately 5.6 cm (or slightly longer for accuracy).

5. Draw Another Arc: Without changing the compass width, draw another arc below the line segment from point A. Ensure that the arcs intersect the line.

6. Connect Intersection Points: Use the ruler and pencil to draw a straight line connecting the two intersection points on the line. This line segment will be 5.6 cm in length.

7. Label the Endpoint: Label the endpoint of the line segment as point B.

Now, you have constructed a line segment AB with a length of 5.6 cm using a ruler and compasses.

To compare the given numbers:

1. 7
2. 12
3. 540
4. 71,25,400

We'll start by comparing the numbers at the highest place value, and if necessary, move on to the next highest place value until a clear winner is determined.

Looking at the numbers:

• 7 is the smallest.
• 12 is greater than 7.
• 540 is greater than 12.
• 71,25,400 is greater than 540.

So, the greatest number among the given numbers is 71,25,400.

To find out by how much it is greater than the next greatest number, we'll subtract the next greatest number (540) from the greatest number (71,25,400):

71,25,400−540=71,24,86071,25,400−540=71,24,860

So, 71,25,400 is greater than 540 by 71,24,860.
