Julie has 3 times as many stickers as Shannon. Shannon has
37 as many stickers as Opal. If the three of them have a total of 114 stickers, how many stickers does Opal have?

3x1 |
7x1 |
9 u |
3 u |
7 u |
The number of stickers that Shannon has is repeated. Make the number of stickers that Shannon has the same. LCM of 1 and 3 is 3.
Total number of stickers that the three of them have
= 9 u + 3 u + 7 u
= 19 u
19 u = 114
1 u = 114 ÷ 19 = 6
Number of stickers that Opal has
= 7 u
= 7 x 6
= 42
Answer(s): 42
