12 students have more than 5 pairs of sneakers
Step-by-step 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
![\begin{gathered} y=x*(p)/(100) \\ where\text{ y is the value } \\ x\text{ is the number} \\ p\text{ is the percentage} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/x9h61e3f86cnf7yexb6ymjde179hxywdkj.png)
so
Step 1
a)let
![\begin{gathered} number=\text{ 30} \\ percentage\text{ = 40 \%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/nxqawj30zfcpazrb3bhdmkdgifuugl9myr.png)
b) now, replace
![\begin{gathered} y=x(p)/(100) \\ y=30*(40)/(100) \\ y=30*0.4 \\ y=12 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/3nbsinb03rb42ok0fiyv05nkl5esf8z3uk.png)
thereforem
