(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 7 is 7.
1x72x7 of total money =
79 of remaining amount
714 of total money =
79 of remaining amount
Fraction of her money that she spent on the blouse
=
BlouseTotal =
514 (b)
Cost of the blouse = 5 u
5 u = 90
1 u = 90 ÷ 5 = 18
Cost of the skirt and the jumpsuit
= 2 u
= 2 x 18
= $36
Cost of the jumpsuit = 1 p
Cost of the skirt = 5 p
Total cost of the jumpsuit and the skirt
= 1 p + 5 p
= 6 p
6 p = 36
1 p = 36 ÷ 6 = 6
Amount that the skirt was more than the jumpsuit
= 5 p - 1 p
= 4 p
= 4 x 6
= $24
Answer(s): (a)
514; (b) $24
