## Math Answers

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
