Given:
Kai spends 15% of a school day in science class
he spends 75 minutes in science class
We need to find, how many minutes does he spend in the school
so, let he spend x minutes in the school
so,
15% of x = 75
Solve for x :
[tex]\begin{gathered} 15\%\cdot x=75 \\ 0.15\cdot x=75 \\ \\ x=\frac{75}{0.15}=\frac{7500}{15}=500 \end{gathered}[/tex]so, the answer will be 500 minutes
