Barbara has 4 times as many stickers as Vanessa. Vanessa has
38 as many stickers as Rachel. If the three of them have a total of 230 stickers, how many stickers does Rachel have?
| Barbara |
Vanessa |
Rachel |
| 4x3 |
1x3 |
|
| |
3x1 |
8x1 |
| 12 u |
3 u |
8 u |
The number of stickers that Vanessa has is repeated. Make the number of stickers that Vanessa has the same. LCM of 1 and 3 is 3.
Total number of stickers that the three of them have
= 12 u + 3 u + 8 u
= 23 u
23 u = 230
1 u = 230 ÷ 23 = 10
Number of stickers that Rachel has
= 8 u
= 8 x 10
= 80
Answer(s): 80
