Question

Find the whole quantity if 2.5% of it is 25.

Answer 1

Answer:

1000

Step-by-step explanation:

Lets assume the quantity to be X.

$x * 2.5% = 25$

$x * \frac{2.5}{100} = 25$

We can multiply both sides by  $\frac{100}{2.5}$  to isolate x.

$x = 25 * \frac{100}{2.5}$

$x = 25* \frac{1000}{25}$

The 25's cancel out, leaving:

$x = 1000$

Answer 2

Answer:1000

Step-by-step explanation:

2.5%×a=25

2.5/100×a=25

a=1000
