32 lollies (lol) per hour for kaihi and 32 per 3 hours for her sister...

Answer 8

Forget about the 32 lollies and consider it as one task to accomplish.
Then to accomplish that task Kaihi (k) spent k hours and her sister (s) s hour.
To accomplish the task together, let say, they spent x hours,
Thus this must hold true:\[\frac{ 1 }{ k }+\frac{ 1 }{ s }=\frac{ 1 }{ x }\]\[\frac{ 1 }{ 1 }+\frac{ 1 }{ 3 }=\frac{ 1 }{ x }\] soving for x you will get \[x =\frac{ 3 }{ 4 }hr\]

Answer 9

so 32*t + 32*t/3 = 32 lollies

Answer 11

nahhh sorry is there a easyer way or the fractions work just need to no how you found the answers

1/k of the task is completed by K
1/s of the task completed by S
1/x of the task completed by both.

Answer 13

Answer 14

Maybe a little simpler:

Kaihi 96 in 3 hours
Sister 32 in 3 hours

Together 128 in 3hours and now you want

That's for 128 lollies and u want 32 so

3 hours * 32/128 = 96/128 = 3/4 hour
