Answer :
1. The number of hours of science homework that Kalani have on Thursday is 1 1/2 hours.
2. The hours of science homework that she have for the whole school week is 4 1/2 hours.
How to calculate the value?
From the information, Kalani started off with 3/4 hour on Monday and every day after that, she had 1/4 hour more than the day before.
1. This will be illustrated as:
Monday = 3/4 hour
Tuesday = 3/4 + 1/4 = 1 hour
Wednesday = 1 hour + 1/4 hour = 1 1/4 hour
Thursday = 1 1/4 + 1/4 = 1 1/2 hours.
2 The total hours will be the addition of all the values for the days of the week.
= 3/4 + 1 + 1 1/4 + 1 1/2
= 4 1/2 hours.
