Question

a construction company needs to remove 24 tons of dirt from a construction site. They can remove 3/8 tons of dirt each hour. How long will it take to remove the dirt?

Answer 1

Since each hour is 3/8 of a tone then, namely how many times does 3/8 go into 24?  well, is just their quotient.

$\bf 24\div\cfrac{3}{8}\implies \cfrac{24}{1}\div\cfrac{3}{8}\implies \cfrac{24}{1}\cdot\cfrac{8}{3}\implies \cfrac{8}{1}\cdot \cfrac{8}{1}\implies 64$
