Jacob had 5/8 as many toys as Greg. When Greg gave half of his toys to Jacob, he then had 55 fewer toys than his friend. How many toys did Greg have at first?

1 answer

Before exchange:
Greg : x toys
Jacob : (5/8)x or 5x/8

After exchange:
Greg : x/2
Jabob : 5x/8 + x/2

5x/8 + x/2 - (x/2) = 55
5x = 440
x = 88
