Carla spends 6/4 hours exercising everyday for 12 days.She spends 1/2 of her exercise time everyday lifting weights.How much time does Carla spend lifting weights during the 12 days?
I think the answer is this:
6/4hrs.=360min. The answer is 90 hours or
540 minutes 360\4=90
90\2=45
45x12=540min.

Why not just take
(6/4)*(12)*(1/2) hours
or
= 9 hours
Your answer of 540 minutes is correct, but why switch to minutes when they weren't even mentioned?
Secondly, what textbook would leave the fraction as 6/4 in "Carla spends 6/4 hours ...." ?
(6/4)*(12)*(1/2) hours
or
= 9 hours
