Answer 1

We conclude that Michael worked for a total of 11.46 hours in the weekend.

How much time did he work on the weekend?

We know that during the weekend, the times that he used for each task are:

• (6 + 3/7) hours to do his homework.
• 4.37 hours to clean his room.
• 2/3 hours to walk the dog

The total time is given by the sum between the above numbers, where the difficulty is the fact that the 3 numbers are in different notations (decimal, fraction, and mixed).

The sum is:

S = (6 + 3/7) h + 4.37 h + 2/3 h

The easier way to do this, is to write the 3 numbers in decimal form:

2/3 = 0.66

6 + 3/7 = 6 + 0.43 = 6.43

Then the total time is:

S = 6.43 h + 4.37h + 0.66h = 11.46 h

We conclude that Michael worked for a total of 11.46 hours in the weekend.
