19 of his remaining money on a blazer. If he still had

9 u |
1 u |
8 u |
The amount that Liam had left is the same. Make the numerators the same. LCM of 4 and 8 is 8.
4x29x2 of his money =
89 of his remaining money
818 of his money =
89 of his remaining money
Amount that Liam spent on the skirt = 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Amount that Liam had at first
= 18 u
= 18 x 10
= $180
Answer(s): $180
