Answer:

The unit rate that ling uses for bananas per each smoothie is (3/1) bananas per smoothie

Explanation:

Ling uses 21 bananas to make 7 fruit smoothies. Total of bananas B = 21. Total of smoothies S =7.

The unit rate U is the relationships B divided by S.

U = B/S

U = 21 bananas / 7 smoothies

U = 21/7 Bananas per smoothies.

We can use the equivalent fractions to find the unit rate. 21 can be expressed as 7*3. 7 can be expressed as 7*1. We can simplify the number 7 in numerator and denominator.

U = (7*3)/(7*1)

U = 3/1.

Finally, the unit rate is 3/1 bananas per smoothie.
