Question

Liam mixed together quarts of orange juice and quarts of pineapple juice. Then he added quarts of seltzer to make punch. How much more juice than seltzer did Liam use to make punch?

Answer 1

Answer:

$2\frac{1}{4}$

Step-by-step explanation:

Question has missing details (See attachment).

Given

$Orange\ Juice = 1\frac{1}{4}quart$

$Pineapple\ Juice = 2\frac{1}{2}quart$

$Seltzer = 1\frac{1}{2}quart$

Required

Determine how much juice than seltzer used.

To do this, we first calculate the total amount of juice

$Juice = Orange + Pineapple$

$Juice = 1\frac{1}{4} + 2\frac{1}{2}$

$Juice = \frac{5}{4} + \frac{5}{2}$

Take LCM

$Juice = \frac{5+10}{4}$

$Juice = \frac{15}{4}$

Then subtract the amount of seltzer used.

$Juice - Seltzer = \frac{15}{4}-1\frac{1}{2}$

$Juice - Seltzer = \frac{15}{4}-\frac{3}{2}$

Take LCM

$Juice - Seltzer = \frac{15 - 6}{4}$

$Juice - Seltzer = \frac{9}{4}$

$Juice - Seltzer = 2\frac{1}{4}$

The amount of juice used more than seltzer is $2\frac{1}{4}$
