12 students have more than 5 pairs of sneakers
Explanationthe 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
[tex]\begin{gathered} y=x*\frac{p}{100} \\ where\text{ y is the value } \\ x\text{ is the number} \\ p\text{ is the percentage} \end{gathered}[/tex]
so
Step 1
a)let
[tex]\begin{gathered} number=\text{ 30} \\ percentage\text{ = 40 \%} \end{gathered}[/tex]
b) now, replace
[tex]\begin{gathered} y=x\frac{p}{100} \\ y=30*\frac{40}{100} \\ y=30*0.4 \\ y=12 \end{gathered}[/tex]
thereforem
12 students have more than 5 pairs of sneakers
I hope this helps you
