1 u |
8 u |
The amount that Pierre had left is the same. Make the numerators the same. LCM of 4 and 8 is 8.
4x27x2 of his money =
89 of his remaining money
814 of his money =
89 of his remaining money
Amount that Pierre spent on the sweater = 5 u
5 u = 70
1 u = 70 ÷ 5 = 14
Amount that Pierre had at first
= 14 u
= 14 x 14
= $196
Answer(s): $196
