If I ate 5 goldfish Susan ate 8 goldfish and there are 1/8 goldfish left how many goldfish were there

Let f represent the original number of goldfish.

Then: f - (1/8) f = (5+8). Thus, (7/8) f = 13, and f = (8/7) (13) = 14.9. This makes little sense! Ensure that you have copied down this problem comletely and accurately.
