Question

In a fish tank, 4/9 of the fish have a red stripe on them. If 12 of the fish have red stripes, how many total fish are in the tank?

Answer 1

Answer: If 4/9 of the fish have a red stripe, we can determine the total number of fish in the tank by dividing the number of fish with red stripes by the fraction of fish with red stripes. This gives us 12 / (4/9) = 12 * (9/4) = 27 fish. So, there are 27 fish in the tank.

Answer 2

`(4)/(9) x = 12`

`x = 12 * (9)/(4)`

`12 * 9 = 108`

`4 * 1 = 4`

`x = (108)/(4)`

`x = 27`

There are 27 fish in the tank. Hope this helps.
