(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 5 is 5.
1x52x5 of total money =
57 of remaining amount
510 of total money =
57 of remaining amount
Fraction of her money that she spent on the skirt
=
SkirtTotal =
310 (b)
Cost of the skirt = 3 u
3 u = 60
1 u = 60 ÷ 3 = 20
Cost of the dress and the blazer
= 2 u
= 2 x 20
= $40
Cost of the blazer = 1 p
Cost of the dress = 3 p
Total cost of the blazer and the dress
= 1 p + 3 p
= 4 p
4 p = 40
1 p = 40 ÷ 4 = 10
Amount that the dress was more than the blazer
= 3 p - 1 p
= 2 p
= 2 x 10
= $20
Answer(s): (a)
310; (b) $20
