Jack spent $105 on a dress. He spent
111 of his remaining money on a skirt. If he still had
59 of his money left, how much did he have at first?

5x2 |
| 7 u |
1 u |
10 u |
The amount that Jack had left is the same. Make the numerators the same. LCM of 5 and 10 is 10.
5x29x2 of his money =
1011 of his remaining money
1018 of his money =
1011 of his remaining money
Amount that Jack spent on the dress = 7 u
7 u = 105
1 u = 105 ÷ 7 = 15
Amount that Jack had at first
= 18 u
= 18 x 15
= $270
Answer(s): $270
