Eli is making slime. His recipe calls for 2/3 cup of glue for every
3/4 cup of laundry detergent. How many cups of glue does he need for 1 cup of
laundry detergent?
He will need 2/3 of a cup. You can do this by setting up a proportion, so (2/3)/(3/4) = x/1. Then you would get 2/3 = 3/4x Divide both sides by 3/4 X = 8/9
