(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 blouse
=
BlouseTotal =
718 (b)
Cost of the blouse = 7 u
7 u = 35
1 u = 35 ÷ 7 = 5
Cost of the dress and the jumpsuit
= 2 u
= 2 x 5
= $10
Cost of the jumpsuit = 1 p
Cost of the dress = 4 p
Total cost of the jumpsuit and the dress
= 1 p + 4 p
= 5 p
5 p = 10
1 p = 10 ÷ 5 = 2
Amount that the dress was more than the jumpsuit
= 4 p - 1 p
= 3 p
= 3 x 2
= $6
Answer(s): (a)
718; (b) $6
