Hehe! I had the same initial thought...then I realized they were testing the kids on multiplication and division of fractions within the model :oops: really gotta combine all those \"topics\". I loike!

Yes 24hr-mum, it is from CH.

I only managed to figure out 3 for $4. Then I tried to divide $4 by 3.
Didn’t occur to me to consider the multiples of 3 which is 21 and 24. Silly me.

Hi All!


Pls help in the following Q
corvan has 26 toy trains and 8 times as many stickers . How many stickers have in all?
Thanks

[24hr-mum]

do u mean how many stickers he has? if so, its just 8x26

if u mean how many he has of both items, then its 9 times of 26 (ie 8 times of stickers and 1 time of toy trains)

[smartmummy]

I bit confuse with this sentence "8 times as many stickers"

toy trains = 26
stickers=??
usually they said number of girls thrice as many as boys.

[just888]

smartmummy,

I also interpret as stickers = 8x26.
