Austin went to the science museum. He was there for 2 hours.

He spent \(\frac{3}{5}\) of his time doing experiments.

He spent \(\frac{1}{3}\) 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.

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

Austin spent 8 minutes looking at skeletons, which is equivalent to 15 1 ​ of his total time at the science museum. He spent 72 minutes doing experiments and 40 minutes at the water station. The calculations involve finding fractions of 120 total minutes.
