MULTI-STEP RATIO PROBLEMS

2
METHODS FOR SOLVING FRACTION OFF SALES PROBLEMS: Method 1: Method 1: Draw a tape diagram. Method 2 Method 2 : Subtract the fraction of the price from the original price. Method 3 Method 3 : Find the fractional part of the price being paid by subtracting the fraction of the price from 1 whole.

3
EXAMPLE: A store advertises its end of the season sale with shoes at ¼ off the original price (called the discount rate). a) If the original price of the shoes is $40, and they are advertised as ¼ off, what is the sale price?

4
METHOD 1 Tape Diagram $40 ¼ off the original price is: 10 + 10 +10 = $30 $10

5
METHOD 2 Subtract ¼ of the price from the original price. $40 – 1 (40) 4 = 40 – 10 = $30

6
METHOD 3 Find the fractional part of the price being paid by subtracting ¼ of the price from 1 whole. ( 1 - 1 ) 40 4 = 3. 40 4 = $30
