| Before |
8x7 =
56 u |
7x8 =
56 u |
| Change |
- 5x7 =
- 35 u |
- 2x8 =
- 16 u |
| After |
3x7 =
21 u |
5x8 =
40 u |
The amount that Charlie and Ken each earned in a month is the same. Make the amount the same. LCM of 8 and 7 is 56.
Amount that Charlie saved more than Ken
= 35 u - 16 u
= 19 u
19 u = 50
1 u = 50 ÷ 19 = 50
Amount that Ken saved in a month
= 16 u
= 16 x 50
= $800
Answer(s): $800
