Reymel's Fraction Scribepost

Textbook 6.2 - 5a, 5d, 9, 12

5a.
                                     

Share 3/5 between 2 groups. First thing you do is change the whole number (2) and turn it into an improper fraction (2/1). You try and find the reciprocal which is 1/2 and you multiply it to get 1 whole. Now, what you do to the bottom, you must do to the top. So 3/5 multiply by 1/2 equals 3/10. Now if you divide 3/10 and 1, it would still be 3/10.


5d.

Share 2/3 between 6 groups. First thing you do is change 6 into 6/1 and multiply it by the reciprocal, which is 1/6. The product would then be 6/6 or 1. Now what you do to the bottom, you must do to the top as I said before. So 2/3 multiply by 1/6 equals 2/18 and when you divide 2/18 by 6/6 or 1, I would still have the same answer (2/18).

9. Ingrid runs three laps of a track in 1/4 hour. On average, how much time does she take to run one lap? Express your answer.
a) as a fraction of an hour.

b) in minutes

12. It takes 4/5 of a roll of ribbon to wrap six packages. What fraction of a roll does it take to wrap three packages? 

It takes 2/5 of a roll to wrap three packages because it takes 4/5 of roll to wrap six packages. That means it would take half as much rolls to use for three packages because 3 is half of 6.

  7. Good job Reymel! You explained how to answer the questions very clearly. You also filled in the pieces (picture) with different colors which makes it also help explain your answers. Maybe next time you should add a video and a link for a game because some people understand them easier by playing games or watching a video. And you could have made some of the words bigger or at least highlighted them.
