Xylia has 4 times as many stickers as Sarah. Sarah has
38 as many stickers as Betty. If the three of them have a total of 253 stickers, how many stickers does Betty have?

4x3 |
1x3 |

3x1 |
8x1 |
12 u |
3 u |
8 u |
The number of stickers that Sarah has is repeated. Make the number of stickers that Sarah 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 = 253
1 u = 253 ÷ 23 = 11
Number of stickers that Betty has
= 8 u
= 8 x 11
= 88
Answer(s): 88
