solution

To decide which equation you can use to find

look for numbers and words in the problem that talk about fish.

Gavin won the raffle at the zoo and gets to feed the dolphins! The dolphin trainer gives Gavin a bucket of fish to divide evenly among 3 dolphins. Each dolphin gets 6 fish.

The bucket has

fish in it. When Gavin divides them evenly among 3 dolphins, each dolphin gets 6 fish. This can be represented by an equation using division.

f	÷	3	=	6

Number of fish in the bucket		Number of dolphins		Number of fish each dolphin gets

Division can also be written using a fraction, so the equation

can be used to find the number of fish in the bucket before the dolphins are fed.

Solve this equation for

Multiply both sides by 3

There are 18 fish in the bucket before the dolphins are fed.
