From the decimal form of the fractions, we can see that see that chocolate bars are the same in size and mass.) My friend eats pieces, which means she eats is equivalent to. and is equivalent > From the diagram, we can also > Then my friend and I did not eat equivalent. (Note: This reasoning assumes that the =. = =.. From the diagram, the light grey circles show the basketballs that my class keeps. of basketballs is basketballs. The dark grey circles show the basketballs that the grade class keeps. of basketballs is basketballs. The white circles show the basketballs that the grade class keeps. There are basketballs left for the grade class. Therefore, my class gets the most basketballs.

For example, Jake has boxes with chocolate bars in each box. If Jake sold boxes of his chocolate bars, how many bars did he sell? Solution: He sold boxes of chocolate bars, or bars. Lesson Answers (continued from page.). Answers may vary. For example: Colin runs km in min and Emily runs km in the same amount of time. Who ran the farthest in min? Use a model to solve the problems. Answer: can be written as an improper fraction as The fractions and can be modelled using fraction circles, and then the amounts compared. From the model we can see that Lesson Answers (continued from page.) c),,, is larger than This means that Colin ran the farthest. / / / / / / / / / / / / / / / / / / d),,, / / / / / / / / / / / / / / / Copyright Thomson Nelson
