It took Mark a total of 4 hours 40 minutes to clean the garage and cut the grass. If it took 1 hour 45 minutes to cut the grass, how long did it take him to clean the garage?

THANKS!

Whoo! I love meh some math, don't you? (sarcastic tone. :D )

To solve this you'll need to do simple subtraction.

Step 1:
Take away the 5 from the "45"... then it's easier to solve with, just add it at the end. :)

Step 2:
Figure out how long that is
60×4 =240 = 40 = 280 minutes.

Step 3: Do the same for the "Grass Cutting"
60 + 40 = 100

Step 4:
100 + 5 = 105
Add on the +5 that we took away in the beginning.

Step 5:
Subtract! :)
175 minutes.

Step 6:
Make it a "time" again by multiplying! Guess what, your on your on. :D

You can get the answer by subtracting the time it took Mark to cut the grass from the total amount of time it took him to do the chores. So 4 hours and 40 minutes minus 1 hour and 45 minutes is 2 hours and 55 minutes
