(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 8 is 8.
1x82x8 of total money =
811 of remaining amount
816 of total money =
811 of remaining amount
Fraction of her money that she spent on the blouse
=
BlouseTotal =
516 (b)
Cost of the blouse = 5 u
5 u = 35
1 u = 35 ÷ 5 = 7
Cost of the blazer and the jacket
= 3 u
= 3 x 7
= $21
Cost of the jacket = 1 p
Cost of the blazer = 6 p
Total cost of the jacket and the blazer
= 1 p + 6 p
= 7 p
7 p = 21
1 p = 21 ÷ 7 = 3
Amount that the blazer was more than the jacket
= 6 p - 1 p
= 5 p
= 5 x 3
= $15
Answer(s): (a)
516; (b) $15
