(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 blazer
=
BlazerTotal =
310 (b)
Cost of the blazer = 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Cost of the coat and the sweater
= 2 u
= 2 x 6
= $12
Cost of the sweater = 1 p
Cost of the coat = 5 p
Total cost of the sweater and the coat
= 1 p + 5 p
= 6 p
6 p = 12
1 p = 12 ÷ 6 = 2
Amount that the coat was more than the sweater
= 5 p - 1 p
= 4 p
= 4 x 2
= $8
Answer(s): (a)
310; (b) $8
