(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 8 is 8.
1x82x8 of total money =
811 of remaining amount
816 of total money =
811 of remaining amount
Fraction of her money that she spent on the vest
=
VestTotal =
516 (b)
Cost of the vest = 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Cost of the coat and the shirt
= 3 u
= 3 x 12
= $36
Cost of the shirt = 1 p
Cost of the coat = 5 p
Total cost of the shirt and the coat
= 1 p + 5 p
= 6 p
6 p = 36
1 p = 36 ÷ 6 = 6
Amount that the coat was more than the shirt
= 5 p - 1 p
= 4 p
= 4 x 6
= $24
Answer(s): (a)
516; (b) $24
