Joelle, Cindy, Lee and Cathy shared some stickers. Joelle and Cindy took
16 of the total number of stickers while Lee and Cathy took the rest. Cindy had twice as many stickers as Joelle and Cathy had 16 stickers. Given that Cathy had twice as many stickers as Cindy, how many stickers were there altogether?

Number of stickers that Cindy had is repeated. Make the number of stickers that Cindy had the same. LCM of 2 and 1 is 2.
Number of stickers that Cathy had = 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Total number of stickers
= 18 u
= 18 x 4
= 72
Answer(s): 72
