(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 blazer
=
BlazerTotal =
314 (b)
Cost of the blazer = 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Cost of the shirt and the coat
= 4 u
= 4 x 5
= $20
Cost of the coat = 1 p
Cost of the shirt = 4 p
Total cost of the coat and the shirt
= 1 p + 4 p
= 5 p
5 p = 20
1 p = 20 ÷ 5 = 4
Amount that the shirt was more than the coat
= 4 p - 1 p
= 3 p
= 3 x 4
= $12
Answer(s): (a)
314; (b) $12
