In a fish tank 8/11 of the fish have red stripes on them. If 16 of the fish have red stripes, how many total fish are in the tank

Hi there, let x be the number of fish. We know 8/11 of the fish have a red stripe and 16 of the fish have a red stripe. Let's set up a problem, 8/11x=16, 10/x=16*11/8, 10/x=2*11, 10/x=22. Therefore, there are 22 fish in the tank.

There are 22 total fish in the tank because 8 got doubled so 11 would also have to get doubled
