Juan has 18 fish that he needs to put into tanks. each tank can hold 3 fish. his father gave him 2 fish tanks, and his mother gave him 3. write an equation with a variable and figure out how many more fish tanks he needs

He needs 1 more fish tank.

Step-by-step explanation:

18 / 3 = X    (X equals the number of fish tanks he needs)

2 + 3 = 5 fish tanks

5 x 3 = 15 fish

18 -15 = 3

Since 5 fish tanks can hold 15 fish he will need 6 fish tanks to hold his 18 fish.  He will need 1 more fish tank.
