Shiyun has 2 times as many beads as Elyse. Elyse has
27 as many beads as Erika. If the three of them have a total of 143 beads, how many beads does Shiyun have?
Shiyun |
Elyse |
Erika |
2x2 |
1x2 |
|
|
2x1 |
7x1 |
4 u |
2 u |
7 u |
The number of beads that Elyse has is repeated. Make the number of beads that Elyse has the same. LCM of 1 and 2 is 2.
Total number of beads that the three of them have
= 4 u + 2 u + 7 u
= 13 u
13 u = 143
1 u = 143 ÷ 13 = 11
Number of beads that Shiyun has
= 4 u
= 4 x 11
= 44
Answer(s): 44
