If Jim has 78 balls and Kim has 8 times more then Jim how much does Kim has ?

Answer 1

K = 8J = 8 times Jim's balls = Kim's balls

J= 78 balls for Jim

K = 8(78)

K = 624 balls for Kim

Unless, possibly, but less likely, the problem intended to say Kim had 8 times "more" than Jim, meaning the difference between their ball numbers = 8 times Jim's 78

then, K-J = 8(78)

K -78 = 8(78)

K = 9(78) = 702 balls for Kim
