| Before |
7x4 =
28 u |
3x5 =
15 u |
| Change |
- 2x4 =
- 8 u |
- 2x5 =
- 10 u |
| After |
5x4 =
20 u |
1x5 =
5 u |
Comparing Victoria
and Opal in the end |
4x5 =
20 u |
1x5 =
5 u |
The amount that Victoria had in the end is repeated. Make the amount that Victoria had in the end the same. LCM of 4 and 5 is 20.
Amount that Opal had less than Victoria
= 28 u - 15 u
= 13 u
13 u = 195
1 u = 195 ÷ 13 = 15
Amount that Victoria had at first
= 28 u
= 28 x 15
= $420
Answer(s): $420
