Question

Percy prepared 22 kilograms of dough after working 5 hours.How many hours did Percy work if he prepared 35.2 kilograms of dough?

Answer 1

Given data:

The amount of cake Percy prepared after working 5 hours is 22 kg.

The expression for the given statement is,

$\begin{gathered} 22\operatorname{kg}\text{ =5 hours} \\ 1\operatorname{kg}\text{ =}\frac{5}{22}\text{ hours} \end{gathered}$

Multiplied the above expression by 35.2 on both sides.

$\begin{gathered} 35.2(\text{ 1 kg)=35.2(}\frac{5}{22}\text{ hours)} \\ 35.2\text{ kg= 8 hours} \end{gathered}$

Thus, Percy need 8 hours to prepare 35.2 kg cake.
