Math Question: if you use 2 parts starch to 3 parts glue how many cups of glue do you need if you use 12 cups of starch

This would be a proportion we need to set up. Let’s set it up as Starch Starch ———— = ————- Glue Glue On the left we can use the initial ratio they gave us and then on the right we can use the final amounts. 2 12 — = — 3 X Now you can cross multiply to get: 2x=36 Now divide 2 on both sides and get X=18 cups of glue
