(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 = 36
1 u = 36 ÷ 3 = 12
Cost of the skirt and the sweater
= 4 u
= 4 x 12
= $48
Cost of the sweater = 1 p
Cost of the skirt = 5 p
Total cost of the sweater and the skirt
= 1 p + 5 p
= 6 p
6 p = 48
1 p = 48 ÷ 6 = 8
Amount that the skirt was more than the sweater
= 5 p - 1 p
= 4 p
= 4 x 8
= $32
Answer(s): (a)
314; (b) $32
