| Before |
8x2 =
16 u |
3x3 =
9 u |
| Change |
- 5x2 =
- 10 u |
- 2x3 =
- 6 u |
| After |
3x2 =
6 u |
1x3 =
3 u |
Comparing Tina
and Fanny in the end |
2x3 =
6 u |
1x3 =
3 u |
The amount that Tina had in the end is repeated. Make the amount that Tina had in the end the same. LCM of 2 and 3 is 6.
Amount that Fanny had less than Tina
= 16 u - 9 u
= 7 u
7 u = 238
1 u = 238 ÷ 7 = 34
Amount that Tina had at first
= 16 u
= 16 x 34
= $544
Answer(s): $544
