Nick and Harry earned the same amount each month. Nick saved
56 of his pay and Harry saved
27 of his pay. Nick saved $70 more than Harry in a month. How much did Harry save in a month?

Nick |
Harry |
Before |
6x7 = 42 u |
7x6 = 42 u |
Change |
- 5x7 = - 35 u |
- 2x6 = - 12 u |
After |
1x7 = 7 u |
5x6 = 30 u |
The amount that Nick and Harry each earned in a month is the same. Make the amount the same. LCM of 6 and 7 is 42.
Amount that Nick saved more than Harry
= 35 u - 12 u
= 23 u
23 u = 70
1 u = 70 ÷ 23 = 70
Amount that Harry saved in a month
= 12 u
= 12 x 70
= $840
Answer(s): $840
