Question

Emma Punch with 3/4 gallons of pineapple juice 1 1/2 gallons of orange juice and 7/8 gallons of apple juice how much gallons of Ginger ale does she need to add to make the total of 4 gallons of punch

Answer 1

Answer:

7/8 gallons of Ginger ale

Step-by-step explanation:

Total gallons of punch mixture =  gallons of pineapple juice + orange juice + gallons of apple juice + gallons of Ginger ale

Given gallons of pineapple juice = 3/4 gallons

Orange juice = 1 1/2 gallons

Gallons of apple juice = 7/8

Total gallons of punch = 4 gallons

On substituting into the formula above:

4 = $\frac{3}{4} +\frac{3}{2}+\frac{7}{8}+Gallons\ of\ ginger\ ale$

$4=\frac{6+12+7}{8} + Gallons\ of\ ginger\ ale$]

gallons of ginger ale = $4-\frac{25}{8}$

gallons ginger ale = $\frac{7}{8}$

She needs 7/8 gallons of Ginger ale to make the total of 4 gallons of punch

Answer 2

Answer:

Emma would need 7/8 gallons of Ginger Ale to make the total of 4 gallons of punch.

Step-by-step explanation:

In the question, Emma used different quantities of juice to make a punch. To find the remainder, needed to make 4 gallons, we sum up the given quantities, and subtract it from the expected amount.

The summation of the given quantities of juice is as follows;

3/4 + 1 1/2 +7/8 = 25/8

We no subtract the quantity we already have from the expected amount, which is 4 gallons, thus;

4 - 25/8 = 7/8 gallons of Ginger Ale.

To confirm the answer, we sum up all the given quantities. Therefore;

3/4 + 1 1/2 + 7/8 + 7/8 = 4 gallons of punch.
