i learned it in 7th grade
but it went in 1 ear and right out the other.
help please?
$\displaystyle \frac{b}{60} = \frac{5}{8}$
You want to get rid of the fraction. Multiply both sides by 60:
$\displaystyle \frac{b}{60} \cdot 60 = \frac{5}{8} \cdot 60$
$\displaystyle b = \frac{5 \cdot 60}{8} = \frac{300}{8} = \frac{4 \cdot 75}{4 \cdot 2} = \frac{75}{2}$
