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

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

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.

Answer 2

7/8 gallons of Ginger ale

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 =
`(3)/(4) +(3)/(2)+(7)/(8)+Gallons\ of\ ginger\ ale`

`4=(6+12+7)/(8) + Gallons\ of\ ginger\ ale`]

gallons of ginger ale =
`4-(25)/(8)`

gallons ginger ale =
`(7)/(8)`

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