(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 9 is 9.
1x92x9 of total money =
911 of remaining amount
918 of total money =
911 of remaining amount
Fraction of her money that she spent on the blouse
=
BlouseTotal =
718 (b)
Cost of the blouse = 7 u
7 u = 49
1 u = 49 ÷ 7 = 7
Cost of the blazer and the sweater
= 2 u
= 2 x 7
= $14
Cost of the sweater = 1 p
Cost of the blazer = 6 p
Total cost of the sweater and the blazer
= 1 p + 6 p
= 7 p
7 p = 14
1 p = 14 ÷ 7 = 2
Amount that the blazer was more than the sweater
= 6 p - 1 p
= 5 p
= 5 x 2
= $10
Answer(s): (a)
718; (b) $10
