Step-by-step explanation:
1) We can start by simplifying the fraction 2/8 down to 1/4 by dividing the top and bottom by 2. From there, we know that there are 60 minutes in 1 hour, so we can find 1/4 of 60 minutes.
That is 15 minutes. Now it says that Drew did that 4 days in a row. Multiply 15 minutes by 4, and we will get 60 minutes, which equals 1 hour.
2) Now let's solve using the same process. 3/8 of an hour is 22.5 minutes which is 22 minutes and 30 seconds.
If he did this for 5 days in a row, lets multiply 22.5 by 5; that is 112.5 which is 112 minutes and 30 seconds. This is 1 hour 52 minutes and 30 seconds.
3) Now use the same process. 2/8 = 1/4. 1/4 of 60 minutes = 15.
15 x 5 = 75 minutes = 1 hour and 15 minutes.
4) 8 x 5 = 40 hours
