Answer 1

15a. False, because Bobby would have to be 6 feet to be 4 times the size of Kenny.

`4 * 1 (1)/(2) \\ 4 * (3)/(2) \\ (12)/(2) \\ 6`

15b. True, because 1 and a half times 3 is 4 and a half.

`3 * 1 (1)/(2) \\ 3 * (3)/(2) \\ (9)/(2) \\ 4 (1)/(2)`

15c. True, because 1 and a half times 5 is 7 and a half.

`5 * 1 (1)/(2) \\ 5 * (3)/(2) \\ (15)/(2) \\ 7 (1)/(2)`

15d. False, because Bobby's height times 2 would be 9.

`2 * 4 (1)/(2) \\ 2 * (9)/(2) \\ (18)/(2) \\ 9`
