Hilda has 3 times as many beads as Shiyun. Shiyun has
38 as many beads as Raeann. If the three of them have a total of 180 beads, how many beads does Raeann have?
Hilda |
Shiyun |
Raeann |
3x3 |
1x3 |

|
3x1 |
8x1 |
9 u |
3 u |
8 u |
The number of beads that Shiyun has is repeated. Make the number of beads that Shiyun has the same. LCM of 1 and 3 is 3.
Total number of beads that the three of them have
= 9 u + 3 u + 8 u
= 20 u
20 u = 180
1 u = 180 ÷ 20 = 9
Number of beads that Raeann has
= 8 u
= 8 x 9
= 72
Answer(s): 72
