Question

A red, a green, and a pink backback are hanging on hooks in the ckassroom. The total weight of the three backpacks is 32 pounds. The red one weighs 9 3/4 pounds. The green one weighs 1 3/4 pounds more than the red one. How much does the pink one weigh?

Answer 1

We know there are 3 backpacks. So when we add the known values 9 3/4 and 1 3/4, we get 11 1/2. So 32- 11 1/2 will give you the pink backpack weight which is 20 and 1/2 pounds.
