Question

Francine uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie , how many cups of pineapple juice does Francine use for 1 cup of orange juice

Answer 1

we know that

Francine uses $2/3$ cup of pineapple juice for every $1/3$ cup of orange juice to make a smoothie

so

by proportion

Find the number of cups of pineapple for one cup of orange juice

$\frac{(2/3)}{(1/3)} \frac{cups\ pineapple}{cups\ orange} =\frac{x}{1} \frac{cups\ pineapple}{cups\ orange}\\ \\x*(1/3)=(2/3) \\ \\x=2\ cups\ pineapple$

therefore

the answer is

$2\ cups\ pineapple\ juice$

Answer 2

Answer:

2  cups of pineapple juice does Francine use for 1 cup of orange juice

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity as 1 such as 3 meter per seconds or 5 miles per hour.

As per the statement:

Francine uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie

then by definition of unit rate:

$\text{Unit rate per cup of orange juice} = \frac{\frac{2}{3}}{\frac{1}{3}}$

Simplify:

$\text{Unit rate per cup of orange juice} = 2$ cups of pineapple juice

Therefore, 2  cups of pineapple juice does Francine use for 1 cup of orange juice
