4x5 =
20 u |
| Change |
- 3x3 =
- 9 u |
- 3x5 =
- 15 u |
| After |
5x3 =
15 u |
1x5 =
5 u |
Comparing Tammy
and Eva in the end |
3x5 =
15 u |
1x5 =
5 u |
The amount that Tammy had in the end is repeated. Make the amount that Tammy had in the end the same. LCM of 3 and 5 is 15.
Amount that Tammy had more than Eva
= 24 u - 20 u
= 4 u
4 u = 148
1 u = 148 ÷ 4 = 37
Amount that Eva had at first
= 20 u
= 20 x 37
= $740
Answer(s): $740
