(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 vest
=
VestTotal =
514 (b)
Cost of the vest = 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Cost of the skirt and the shirt
= 2 u
= 2 x 5
= $10
Cost of the shirt = 1 p
Cost of the skirt = 4 p
Total cost of the shirt and the skirt
= 1 p + 4 p
= 5 p
5 p = 10
1 p = 10 ÷ 5 = 2
Amount that the skirt was more than the shirt
= 4 p - 1 p
= 3 p
= 3 x 2
= $6
Answer(s): (a)
514; (b) $6
