Best ResponseYou've already chosen the best response.0Forget 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 \[x =\frac{ 3 }{ 4 }hr\]

Best ResponseYou've already chosen the best response.1Maybe 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
