A dolphin research team has 248 fish to distribute equally among 4 tanks. The tank will receive ​ (a)   fish per tank.

Answer explanation

To find how many fish each tank receives, divide 248 by 4 using partial quotients. 4 goes into 248 about 60 times (240), leaving 8. Then, 4 goes into 8 exactly 2 times. So, 60 + 2 = 62 fish per tank.
