Leon had 56 paper clips. He gave 3 over 4 of them to joe. Joe gave 2 over 7 of what he recieved to keith.

Answer 1

I'm assuming your asking how many did Keith get?

56*3/4=42 Leon gave to Joe

42*2/7=12 Joe gave to Keith

3/4= 75%

2/7=28.6%

Answer 2

How much did Keith get?
3/4 x 56 = 42 = Joe
2/7 x 42 = 12 = Keith
Clue: the word 'of ' tells us that we need to multiply.
