| Before |
8x4 =
32 u |
7x3 =
21 u |
| Change |
- 5x4 =
- 20 u |
- 6x3 =
- 18 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Hilda
and Barbara in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Hilda had in the end is repeated. Make the amount that Hilda had in the end the same. LCM of 4 and 3 is 12.
Amount that Barbara had less than Hilda
= 32 u - 21 u
= 11 u
11 u = 352
1 u = 352 ÷ 11 = 32
Amount that Hilda had at first
= 32 u
= 32 x 32
= $1024
Answer(s): $1024
