Vanessa and Elyse had an equal number of beads at first. Vanessa used
12 of her beads and Elyse used
110 of her beads. They used 60 beads altogether. How many beads did Elyse have in the end?

Elyse |
| Before |
2x5 =
10 u |
10x1 =
10 u |
| Change |
- 1x5 =
- 5 u |
- 1x1 =
- 1 u |
| After |
1x5 =
5 u |
9x1 =
9 u |
The number of beads that Vanessa and Elyse each had at first is the same. Make the number of beads that Vanessa and Elyse each had at first the same. LCM of 2 and 10 is 10.
Number of beads that Vanessa and Elyse used
= 5 u + 1 u
= 6 u
6 u = 60
1 u = 60 ÷ 6 = 10
Number of beads that Elyse had in the end
= 9 u
= 9 x 10
= 90
Answer(s): 90
