Question

Joshua spent 3/7 of his money on souvenirs on vacation. He has $16 left. How many ounces of peanut butter are there in 1 serving?

Answer 1

To solve, I would first find out what 1/7 of his money is. You find this by dividing 16 by 4.

4/7=$16 (money left over)
--- ----
4     4
1/7=$4

Next, you find 3/7 by multiplying by 3

3x1/7=4x3
3/7=$12
