austin went to the science museum. He was there for 2 hours. he spent 3/5 of his time doing experiments. he spent 1/3 of his time at the water station. He spent the rest of his time looking at skeletons. How long did austin spend looking at skeletons? show all your work, and express your answer as a number of minutes and as a fraction.

Answer 1

3/5 +1/3 =14/15
fraction spend looking on skeletons =1/15

Answer 2

I will change hour to be minute
2 hours =120minute
spent 3/5 of 120 minutes ;120(3/5)=24*3=72
he did his experiments for 72 minutes
72 of 120 is 72/120 =3/5

spent 1/3 of 120 minutes ; 120(1/3)=40
he spent the time at water station for 40 minutes
40 of 120 is 40/120 = 1/3

Looked at the skeletons 120-(72+40)=120-112=8
he spent the time lokking at skeletons for 8 minutes
8 of 120 is 8/120 = 1/15
