(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 dress
=
DressTotal =
314 (b)
Cost of the dress = 3 u
3 u = 51
1 u = 51 ÷ 3 = 17
Cost of the coat and the skirt
= 4 u
= 4 x 17
= $68
Cost of the skirt = 1 p
Cost of the coat = 3 p
Total cost of the skirt and the coat
= 1 p + 3 p
= 4 p
4 p = 68
1 p = 68 ÷ 4 = 17
Amount that the coat was more than the skirt
= 3 p - 1 p
= 2 p
= 2 x 17
= $34
Answer(s): (a)
314; (b) $34
