Step-by-step explanation
if it takes 10 hours to get 50%, then it will take less number of hours to get 32%
We use proportion to solve this question.
If less more divides.
The number of hours it will take to get 32% is
![= (32\% * 10)/(50\%)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/evhhdkhvw2tp7xr5hlbhhowvi2ih9hmg9n.png)
