Question

Last night Davis did homework for 5/6 of an hour. He spent 1/3 of that time working on math. Which model shows the fraction of an hour he worked on math?

Answer 1

5/6 hour = 15/18 hour

one third of 15/18 = 5/18

5/18 * 60 minutes / hour = 0.2777777778 hours

which equals 16 minutes 40 seconds
