| Before |
4x3 =
12 u |
6x2 =
12 u |
| Change |
- 1x3 =
- 3 u |
- 1x2 =
- 2 u |
| After |
3x3 =
9 u |
5x2 =
10 u |
The number of beads that Raeann and Penelope each had at first is the same. Make the number of beads that Raeann and Penelope each had at first the same. LCM of 4 and 6 is 12.
Number of beads that Raeann and Penelope used
= 3 u + 2 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Number of beads that Penelope had in the end
= 10 u
= 10 x 6
= 60
Answer(s): 60
