Question

What is the whole quantity if it's 72% is 0.32 ?
a.51/52
b.36/81
c.12/56
d.7/89​

Answer 1

Answer:

let the quantity is x

then 72% of x is 0.32

that is

$( \frac{72}{100} ) \times x = 0.32 \\ = > x = ( \frac{32}{100} ) \times ( \frac{10 = 0}{72} ) \\ = > x = \frac{32}{72} \\ = > x = \frac{4}{9} = 0.44$
