3-   25% of a number is equal to 1/4 or 0.25 of it.

4-    13% of a number is equal to 0.13 of it.

5-    15 is 12.5% of 120.

Step-by-step explanation:

1. 10% of ________- 8

2.28 is 4% of _________

3.25% of ________

4.13% of______

5.15 is 12.5% of _____

To determine the missing numbers in the statements, the following calculations must be performed:

1-

10 = -8

100 = X

100 x -8 / 10 = X

-800 / 10 = X

-80 = X

Therefore, 10% of -80 is -8.

two-

4 = 28

100 = X

100 x 28/4 = X

2800/4 = X

700 = X

Therefore, 28 is 4% of 700.

 

3-

25% of a number is equal to 1/4 or 0.25 of it.

4-

13% of a number is equal to 0.13 of it.

5-

12.5 = 15

100 = X

100 x 15 / 12.5 = X

1500 / 12.5 = X

120 = X

Therefore, 15 is 12.5% of 120.
