(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 9 is 9.
1x92x9 of total money =
911 of remaining amount
918 of total money =
911 of remaining amount
Fraction of her money that she spent on the shirt
=
ShirtTotal =
718 (b)
Cost of the shirt = 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Cost of the vest and the dress
= 2 u
= 2 x 12
= $24
Cost of the dress = 1 p
Cost of the vest = 3 p
Total cost of the dress and the vest
= 1 p + 3 p
= 4 p
4 p = 24
1 p = 24 ÷ 4 = 6
Amount that the vest was more than the dress
= 3 p - 1 p
= 2 p
= 2 x 6
= $12
Answer(s): (a)
718; (b) $12
