Lynn has 3 times as many beads as Rachel. Rachel has
23 as many beads as Cathy. If the three of them have a total of 44 beads, how many beads does Cathy have?
| Lynn |
Rachel |
Cathy |
| 3x2 |
1x2 |
|
| |
2x1 |
3x1 |
| 6 u |
2 u |
3 u |
The number of beads that Rachel has is repeated. Make the number of beads that Rachel has the same. LCM of 1 and 2 is 2.
Total number of beads that the three of them have
= 6 u + 2 u + 3 u
= 11 u
11 u = 44
1 u = 44 ÷ 11 = 4
Number of beads that Cathy has
= 3 u
= 3 x 4
= 12
Answer(s): 12
