Amilkshake is made by mixing 17 ounces of milk per every 21 ounces of ice cream. how many ounces of milk were added to 114 ounces of milkshake?

To solve this equation, you would need to know how many milkshakes were made. We already know that each milkshake is made up of 17 ounces of milk and 21 ounces of ice cream. 

17+21=38

To find out how many milkshakes were made, we would have to do:

114/38=3

For each milkshake, we use 17 ounces of milk, as said before so we would have to do:

17*3=51.

51 ounces of milk were added to 114 ounces of milkshake.
