| Before |
3x10 =
30 u |
10x3 =
30 u |
| Change |
- 1x10 =
- 10 u |
- 1x3 =
- 3 u |
| After |
2x10 =
20 u |
9x3 =
27 u |
The number of stickers that Raeann and Gabby each had at first is the same. Make the number of stickers that Raeann and Gabby each had at first the same. LCM of 3 and 10 is 30.
Number of stickers that Raeann and Gabby used
= 10 u + 3 u
= 13 u
13 u = 52
1 u = 52 ÷ 13 = 4
Number of stickers that Gabby had in the end
= 27 u
= 27 x 4
= 108
Answer(s): 108
