Let's go shopping! Louis finds some great deals on dresses and earrings. The dress he bought is 3/5 the original of $60. The earrings were 3/8 the original price of $24. How much is his bill beofre tax? How much after 5% GST and 7% PST?

dress: 60/5= __ x 3 = 36.

earrings: 24/8= __ x 3 = 9.

= 45$ before tax.

45 x 12 = $5.40 (tax)

or ...

45 x 0.12 = $5.40 (tax)

*Your total bill will be $50.40

1/4 + 2/4= 3/4, 0.75, 75%

2/3 + 2/3= 1 1/3 or 4/3.

1/10 of 2/5 of 1/3 of 3/4 of 1/5 of 1/2 of 100.

1000 to, 500 to, 100 to, 75 to, 25 to, 10!
