Answer 1

Explanation

Step 1

to find the percentageof any number we need to use the expression

$\begin{gathered} x=a\cdot p\text{ \%} \\ \text{where x is the amount} \\ and\text{ a is the whole amount} \end{gathered}$

so, to know the 15% of $120 we need to replace

a)let

$\begin{gathered} a\text{ = \ 120} \\ p=15\text{ \%} \end{gathered}$

now, replace

$\begin{gathered} x=\text{ \ 120 }\cdot\text{ 15\%} \\ x=120\cdot15\text{ \%} \\ 120\cdot15\text{ \%}=x \end{gathered}$

therefore, the answeris
