Rachel has 4 times as many stickers as Xandra. Xandra has
47 as many stickers as Lynn. If the three of them have a total of 297 stickers, how many stickers does Lynn have?
Rachel |
Xandra |
Lynn |
4x4 |
1x4 |
|
|
4x1 |
7x1 |
16 u |
4 u |
7 u |
The number of stickers that Xandra has is repeated. Make the number of stickers that Xandra has the same. LCM of 1 and 4 is 4.
Total number of stickers that the three of them have
= 16 u + 4 u + 7 u
= 27 u
27 u = 297
1 u = 297 ÷ 27 = 11
Number of stickers that Lynn has
= 7 u
= 7 x 11
= 77
Answer(s): 77
