12 students have more than 5 pairs of sneakers

Step-by-step explanation

the problem says 40% of 30 students have more thatn 5 pairs of sneackers, so to find the number of students we need to find 40% of 30

to find the value of any percentage on a number we can use the formula


\begin{gathered} y=x*(p)/(100) \\ where\text{ y is the value } \\ x\text{ is the number} \\ p\text{ is the percentage} \end{gathered}

so

Step 1

a)let


\begin{gathered} number=\text{ 30} \\ percentage\text{ = 40 \%} \end{gathered}

b) now, replace


\begin{gathered} y=x(p)/(100) \\ y=30*(40)/(100) \\ y=30*0.4 \\ y=12 \end{gathered}

thereforem

12 students have more than 5 pairs of sneakers

I hope this helps you
