Answer 1

Question:

`78\text{ \% of 70}`

78% means

`78\text{ \%=}\frac{\text{78}}{100}`

To proportion, we will have that

`(78)/(100)=(x)/(70)`

Cross multiply, we will have

`\begin{gathered} (78)/(100)=(x)/(70) \\ 100* x=78*70 \\ 100x=5460 \\ \text{divide both sides by 100} \\ (100x)/(100)=(5460)/(100) \\ x=54.6 \end{gathered}`

Hence,

78% of 70 = 54.6
