Subject: Practical uses for division of fraction
Suppose you had 5/8 yds. of a piece of fabric, and you needed 1/4 yd pieces to make appliques or quilt blocks, or something). How many 1/4 pieces could you get from a 5/8 yd. piece? The problem would be 5/8 divided by 1/4... Or, what about having an hour and a half to spend, knowing that each computer game you play takes you a 1/4 hour to complete. You need to know how many quater hours you can use in three halves of an hour, so the problem would be 3/2 divided by 1/4. That is not a great example, because you would probably use minutes rather than parts of an hour. I guess the first one is a bit obsolete, since many people don't sew... what other example could be used with those same numbers? -Gail, for the Teacher2Teacher service
