Helen spent $126 on a jumpsuit. She spent ²₁₁ of her remaining money on a shirt and a vest, after which half her money was left.

1. What fraction of her money did she spend on the jumpsuit?
2. The cost of the vest is ¹₃ the cost of the shirt. How much more does the shirt cost than the vest?

Jumpsuit	Remaining amount
	Shirt	Vest	Left
$126	2		9
1x9			1x9
7 u	2 u		9 u

(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 jumpsuit
= ^Jumpsuit_Total 
= ⁷₁₈ 

(b)
Cost of the jumpsuit = 7 u

7 u = 126

1 u = 126 ÷ 7 = 18

Cost of the shirt and the vest
= 2 u
= 2 x 18
= $36

Cost of the vest = 1 p
Cost of the shirt = 3 p

Total cost of the vest and the shirt 
= 1 p + 3 p
= 4 p

4 p = 36

1 p = 36 ÷ 4 = 9

Amount that the shirt was more than the vest
= 3 p - 1 p
= 2 p
= 2 x 9
= $18

Answer(s): (a) ⁷₁₈; (b) $18
