The amount of time Jill spent to do her homework  

= 9 1/2 hours. which equals to  570 minutes.

Which means, the amount of times Jack needed to do his is  

= 570 minutes x 1.5

= 855 minutes which equals to 14 1/4 hours

hope this helps

Step-by-step explanation:

1) Time spent by Jack = Time spent by Jill * 1  1/2

2) Time spent by Jill = Time spent by Jack ÷  1 1 /2

                                 = 18 1/4 ÷ 1 1/2

                                 = 73/ 4 ÷ 3/2

3) Third number = Sum of three numbers - Sum of two numbers

Sum of two numbers =

Third number = 22 8/15 - 101/6

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

just sum

10 + 10 = 20
