Answer:

12 servings

Step-by-step explanation:

Given:

Evil bunny's carrot soup calls for 5/8 cups of chopped carrots per serving.

If evil bunny has chopped 7 1/2 cups of chopped carrots.

Question asked:

How many servings of carrot soup can he make?

Solution:

<u><em>By unitary method:</em></u>

$\frac{5}{8}$ cups of chopped carrots used for = 1 serving of carrot soup

1 cup of chopped carrots used for = $\frac{1}{\frac{5}{8} }$ = $1\div\frac{5}{8} =1\times\frac{8}{5} =\frac{8}{5}$ servings

$7\frac{1}{2}$ cups of chopped carrots used for = $7\frac{1}{2} \times\frac{8}{5} =\frac{7\times2+1}{2} \times\frac{8}{5} =\frac{15}{2} \times\frac{8}{5}=\frac{120}{10} =12$
