Abel --> 12u...
Sherrie --> 12u...

Hi there,

Thanks!

I too thought it would involve breaking up the models into x units that are divisible by the fractions, i.e. 1/6, 1/4. But I struggled to find these concepts in the books :stupid: - is this correct or would you be able to elaborate a little on the concept?

Hi
concept is the same as adding/subtracting fractions --> find the common denominator. In this case, find lowest common factor ie 12.

cheers.[/quote]Hi,

Thanks! Will look through the rest!

Hi all,


Need help in the following questions for my child. Thanks in advance for any help

Q1) Abel had 42 stickers more than Sherrie at first. Abel use 1/6 of his stickers, while Sherrie used 1/4 of her stickers. After that Abel had 45 more stickers than Sherrie. How many stickers did Abel have at first?

Q2) Gina had a box of RED, BLUE and GREEN counters. The ratio of RED counters to BLUE counters was 5:2. The ratio of BLUE counters to GREEN counters was 3:5.
(a) What was the ratio of RED counters to BLUE counters to GREEN counters? - my kiddo seems to know how to do this
(b) After Gina took out 126 RED counters from the box, 1/3 of the remaining counters were RED. How many counters were left in the box?

Q3) The ratio of the number of beads Kenny has to the number of beads Sarah is 7:5. When Sarah gives 48 beads to Kenny, she has 1/3 of the number of beads Kenny has.
(a) How many beads does Kenny have after receiving the beads from Sarah?
(b) How many beads must Kenny give back to Sarah so that she will have 5 times as many beads as him?
