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.

smartmummy,

I also interpret as stickers = 8x26.

Joe got 3/5 of Ken's marble.

So if ken is 5/5 then joe's is 3/5
Total 8 units for the 2 boys
1 unit is 10
To be equal they needs to be 4 units each.
Hence Ken needs to give 50-40 = 10 marbles to Joe.

does it mean if luke has 7/3, then matthew has 3/3
total 10 units, each unit is 14
and 2units x 2 = 28
luke must give matthew 28 cards?
