Before you move on to the next page, try this problem (borrowing with fractions and whole numbers).
Bruno needs to work for 2 hours and 30 minutes on his homework. He has already worked 45 minutes.
How much time does he have left? How would you solve this? Do you see that there is only 30 minutes
but we'll need to subtract 45 minutes. How will we change one hour to minutes so we can subtract?
Show your work and explain how you borrowed. A minute is a fraction of an hour.
1 HOUR AND 45 MINUTES
