| Before |
2x4 =
8 u |
8x1 =
8 u |
| Change |
- 1x4 =
- 4 u |
- 1x1 =
- 1 u |
| After |
1x4 =
4 u |
7x1 =
7 u |
The number of beads that Jaslyn and Fanny each had at first is the same. Make the number of beads that Jaslyn and Fanny each had at first the same. LCM of 2 and 8 is 8.
Number of beads that Jaslyn and Fanny used
= 4 u + 1 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of beads that Fanny had in the end
= 7 u
= 7 x 8
= 56
Answer(s): 56
