| Before |
3x7 =
21 u |
7x3 =
21 u |
| Change |
- 2x7 =
- 14 u |
- 4x3 =
- 12 u |
| After |
1x7 =
7 u |
3x3 =
9 u |
The amount that Zane and Dylan each earned in a month is the same. Make the amount the same. LCM of 3 and 7 is 21.
Amount that Zane saved more than Dylan
= 14 u - 12 u
= 2 u
2 u = 100
1 u = 100 ÷ 2 = 100
Amount that Dylan saved in a month
= 12 u
= 12 x 100
= $1200
Answer(s): $1200
