Madelaine's Fraction Scribepost

Textbook 6.2 Numbers 4.c, 4.d, 8, and 11.


4. c. 1/5 ÷ 2 =

Share 1/5 between 2 groups.

First you change the whole number into a fraction by putting it over 1. Then you multiply it by the reciprocal which in this case is 2/1 x 1/2 = 2/2 (a whole). What you do to the whole number, you also do it to the fraction, so  1/5 x 1/2 = 1/10 which is the product.





4.d. 5/6  ÷ 4 =  

Share 5/6 between 4 groups.

First you change the whole number into a fraction by putting it over 1.Then you multiply it by the reciprocal which in this case is 4/1 x 1/4 = 4/4 (a whole). What you do to the while number you also do to the fraction, so 5/6 x 1/4 = 5/24 which is the product.



8. The areas of Alberta, Manitoba and Saskatchewan are approximately equal. The sum of their areas are 1/5 of the area of Canada. Express the area of these provinces as the fraction of the area of Canada.

Share 1/5 between 3 groups. (The 3 provinces)

First you change the whole number into a fraction by putting it over 1. Then you multiply it by the reciprocal which in this case is 3/1 x 1/3 = 3/3 (a whole). What you do to the whole number you also do to the fraction, so 1/5 x 1/3 = 1/15 which is the product.




11. Iqaluit has frost on about 3/4 of the days in a year. It has frost on five times as many days as Vancouver. On what fraction of the days of the year does Vancouver have frost?

Share 3/4 between 5 groups.

First you change the whole number into a fraction by putting it over 1. Then you multiply it by the reciprocal which in this case is 5/1 x 1/5 = 5/5 (a whole). What you do to the whole number you also do to the fraction, so 3/4 x 1/5 = 3/20 which is the product.

  12. good job your post was really well made I think besides having a video would be to have a link to a game because in order to have a video that would suffice you would have to make one your self wich can be quite challenging so other than that job well done
