Question

Afruit punch recipe calls for 3 parts of apple juice to 4 parts of cranberry juice. How many liters of cranberry juice should be added to 4.5 L of apple juice?

Answer 1

you must add `6` litres of cranberry juice

Explanation:

"A fruit punch recipe calls for 3 parts of apple juice to 4 parts of cranberry juice"

Meaning: For every 3 litres of apple juice, you must add 4 litres of cranberry juice. That means if you add 6 litres of apple juice, then you must add 8 litres of cranberry juice

Now, if you add 4.5 litres of apple juice, you can think of it this way

`3" apple juice" : 4" cranberry juice"`
`4.5" apple juice": x" cranberry juice"`

`x=(4.5times4)/3`
`x=18/3`
`x=6`

Therefore, you must add `6` litres of cranberry juice

Answer 2

As `3` parts of apple juice are added to `4` parts of cranberry juice

and `4.5` liter of apple juice means each of three parts are

`4.5/3=1.5` liter

and one needs `4` parts of cranberry juice i.e.

`4xx1.5` liter or `6` liter of cranberry juice.
