(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 = 70
1 u = 70 ÷ 5 = 14
Cost of the shirt and the jumpsuit
= 2 u
= 2 x 14
= $28
Cost of the jumpsuit = 1 p
Cost of the shirt = 6 p
Total cost of the jumpsuit and the shirt
= 1 p + 6 p
= 7 p
7 p = 28
1 p = 28 ÷ 7 = 4
Amount that the shirt was more than the jumpsuit
= 6 p - 1 p
= 5 p
= 5 x 4
= $20
Answer(s): (a)
514; (b) $20
