Karen mixed 1/2 cup of orange juice, 3/4 cup of pineapple juive , and 1/3 cup of grapefruit juice. How many cups of juice did she use??

Please help:)

1/2 = 6/12

3/4 = 9/12
1/3 = 4/12

Add, and simplify your answer.

To find the total amount of juice Karen used, you need to add the amounts of orange juice, pineapple juice, and grapefruit juice.

First, let's convert the fractions to a common denominator. The common denominator for 2, 4, and 3 is 12.

So, 1/2 cup is equivalent to 6/12 cup.

Likewise, 3/4 cup is equivalent to 9/12 cup.

And 1/3 cup is equivalent to 4/12 cup.

Now, add the amounts of juice together: 6/12 + 9/12 + 4/12 = 19/12.

Since 19/12 is an improper fraction, we can simplify it.

Divide 19 by 12: 19 ÷ 12 = 1 remainder 7.

So, the answer is 1 and 7/12 cups of juice.
