(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 7 is 7.
1x72x7 of total money =
711 of remaining amount
714 of total money =
711 of remaining amount
Fraction of her money that she spent on the blouse
=
BlouseTotal =
314 (b)
Cost of the blouse = 3 u
3 u = 45
1 u = 45 ÷ 3 = 15
Cost of the jumpsuit and the dress
= 4 u
= 4 x 15
= $60
Cost of the dress = 1 p
Cost of the jumpsuit = 4 p
Total cost of the dress and the jumpsuit
= 1 p + 4 p
= 5 p
5 p = 60
1 p = 60 ÷ 5 = 12
Amount that the jumpsuit was more than the dress
= 4 p - 1 p
= 3 p
= 3 x 12
= $36
Answer(s): (a)
314; (b) $36
