Answer 1

Jerry needs to study for 1 hour to reach his goal.

Explanation:

Monday

1 1/2 = 1 hour, 30 minutes

Tuesday

2/3 of an hour

1 hour = 60 minutes

60 / 3 = 20

2/3 of 60 = 40 minutes

Wednesday

5/6 of an hour

1 hour = 60 minutes

60 / 6 = 10

5/6 of 60 = 50 minutes

How much time he has studied already

1 hour = 60

60 + 30 + 40 + 50 = 180

180 / 60 = 3 hours

How much more time does he need to study

4 - 3 = 1

Jerry needs to study for one more hour.
