(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 dress
=
DressTotal =
516 (b)
Cost of the dress = 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Cost of the jacket and the shirt
= 3 u
= 3 x 8
= $24
Cost of the shirt = 1 p
Cost of the jacket = 3 p
Total cost of the shirt and the jacket
= 1 p + 3 p
= 4 p
4 p = 24
1 p = 24 ÷ 4 = 6
Amount that the jacket was more than the shirt
= 3 p - 1 p
= 2 p
= 2 x 6
= $12
Answer(s): (a)
516; (b) $12
