Question

Ling uses 21 bananas to make 7 fruit smoothies. What is the unit rate that Ling uses for bananas per each smoothie? What is the unit rate? Explain how to use equivalent fractions to find the answer

Answer 1

Answer:

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

Step-by-step 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. 

Answer 2

21/7 divide num and denominator by 7 u will get
3/1 so 3 smoothie is answer
21/7=3/1(equivalent fraction)
