Jenny makes food for her hummingbird feeders. the food is made up of 1 part sugar and 4 parts water. she uses 34 3 4 cup of sugar to make the hummingbird food. how much water should jenny use?

I am assuming that the 34 3 4 cup of sugar means 34 3/4.

Given:
Ratio of sugar to water is 1:4

34 3/4 sugar to quantity of water.

First, we need to convert the mixed fraction into an improper fraction.

34 3/4 = ((34*4)+3)/4 = 139/4

1:4 = 139/4:x
x = 4*139/4
x = 139

Jenny should use 139 cups of water for the 34 3/4 cups of sugar.
