Question

Jenny makes food for her hummingbird feeders. The food is made up of 1 part sugar and 4 parts water. She uses 3434 cup of sugar to make the hummingbird food. How much water should Jenny use?

Answer 1

1:4
when sugar=34
times 34 both sides
34*4=136
1:4=34:136
should use 136 cups of water
that is alot of water
that's a big feeder (8.5 gallons. the water alone weighs about 74.8lb)

should use 136 cups (wow)

Answer 2

1 part is sugar and 4 parts are water of the hummingbird food. They already give you 3,434 cups of sugar. 

1 part = 3,434 
4 part = 3,434 x 4 ... 

part of water missing = 13,736
