Answer :
The tablespoons of lemonade mix that it takes per cup of sparkling water is 0.67 tablespoon.
How to calculate the value?
From the information, a recipe for sparkling lemonade calls for 1/2 tablespoon of lemonade mix and 3/4 cup of sparkling water.
Let the number of tablespoon be represented as x.
Based on the information given, the expression will be:
1/2 / 3/4 = x/1
0.5 / 0.75 = x/1
Cross multiply
0.75 × x = 0.5
0.75x = 0.5
Divide
x = 0.5 / 0.75
x = 0.67
0.67 tablespoon is needed.
