**Additional Example 2A: Converting Customary Units**

Course 1 5-6 Customary Measurements Additional Example 2A: Converting Customary Units Convert 5,000 pounds to tons. Method 1: Use a Proportion Write a proportion using a ratio of equivalent measures. pounds tons 2,000 1 5, m x = Using Proportions 2,000 • x = 1 • 5,000 2000x = 5,000 x = 2.5 5,000 pounds is equal to 2.5 tons.

**Additional Example 2B: Converting Customary Units**

Course 1 5-6 Customary Measurements Additional Example 2B: Converting Customary Units Convert 5,000 pounds to tons. Method 2: Multiply by 1 Multiply by a ratio equal to 1, and cancel the units. 5,000 p m 1 1 ton t 2,000 p 5,000 p = Multiplying by 1 is the same as dividing by the number of pounds in 1 ton. 1 ton t 2,000 = 5,000 = 2.5 tons 5,000 pounds is equal to 2.5 tons.

**5-6 Customary Measurements Check It Out: Example 2B**

Course 1 5-6 Customary Measurements Check It Out: Example 2B Convert 24 pints to cups. Method 2: Multiply by 1 Multiply by a ratio equal to 1, and cancel the units. 24 pt m1 2 ct 1 pt 24 pt = This is actually multiplying by 1 because 1 pint has 2 cups in it. Multiplying by 2c over 1pt is the same as multiplying by 1 because 1 pint has 2 cups in it. 2 c 1 = 24 = 48 cups 24 pints is equal to 48 cups.

**Additional Example 3: Adding or Subtracting Mixed Units of Measure**

Course 1 5-6 Customary Measurements Additional Example 3: Adding or Subtracting Mixed Units of Measure Allison orders a 6-ounce grilled chicken sandwich. Dominic orders a quarter-pound grilled chicken sandwich. Which sandwich weighs more? Explain. First convert a quarter-pound to ounces. ounces pounds 16 1 x .25 Write a proportion using 16 oz = 1 lb. = x = 4 oz Allison’s sandwich weighs more because Dominic’s sandwich is only 4 oz.

Course 1 5-6 Customary Measurements Check It Out: Example 3 Tedd and Fergie go the hardware store to purchase a bag of nails. Tedd buys a bag of nails that weighs 7 pounds 8 ounces. Fergie buys a bag of nails that weighs 128 ounces. Which bag of nails weighs more? Explain. First convert 7 pounds to ounces. ounces pounds 16 1 x 7 Write a proportion using 16 oz = 1 lb. = x = 112 oz + 8 oz x = 120 oz Fergie’s bag of nails weigh more because Tedd’s bag only weighs 120 oz.
