Question

4/5 of a certain number is 64.half of the number is?

Answer 1

Solution-

Let the number be x

Therefore, 4x/5 = 64
                      4x = 320
                         x = 80

Hence, 1/2 of the number = 1/2 * 80 = 40

Answer 2

Answer:

40

Step-by-step explanation:

Given :4/5 of a certain number is 64.

To Find:half of the number is?

Solution:

Let the number be x

Since we are given that 4/5 of a certain number is 64.

So, $\frac{4}{5}x=64$

$4x=64 \times 5$

$4x=320$

$x=\frac{320}{4}$

$x=80$

Hence the number is 80.

Half of number = $\frac{80}{2} =40$

Thus the half of number is 40
