Question

7. If 40% of a given number is 8, then what is 15% of the given number?

Answer 1

Answer:

3

Step-by-step explanation:

First find the given number(x)

40% : 40/100 × x = 8

the value of x is 20.

Next find 15% of 20

15/100 × 20 = 3

Answer 2

Step-by-step explanation:

40% of a given number is 8

40% of a given number is 8

0.4 * x = 8

0.4 x = 8

0.4x = 8

x = 8/0.4

x = 20

So the "given number" is 20

-------------------------------------------------------------------

Now take 15% of that given number:

20*0.15 = 3

So 15% of 20 is 3
