Question

O.6% of a number is 15 find the number.

Answer 1

Let the number be X.

Then,

$\frac{0.6}{x} \times 100 = 15 \\ \\ \frac{60}{x} = 15 \\ \\ \frac{60}{15} = x \\ \\ x = 4$
So the number is 4.

Hope it helps.

Answer 2

Let the unknown number be z.

0.6 of z = 15

0.6/100 × z = 15

6/1000 × z = 15

z = 15 × 1000 / 6

z = 2500

therefore, the unknown number is 2500
