300 * 8 = 2,400
8.) 562 * 7
round 562 to 600
600 * 7 = 4,200
9.) 82 * 15
round 82 to 80 and 15 to 20
80 * 20 = 1,600
10.) 711 * 88

459. i just have to write more so that this is 20 characters long, but the answer is 459
There is one cake
It is divided among x family members, so each gets:
1/x
The father took 1/5 which is 4 times greater than each one's piece. So:
1/5 = 4(1/x)
1/5 = 4/x
x = 20
There are 20 family members so the answer is none of these
