Step 2: Multiply the given measurement by the unit fraction relating the unit given and the unit we want to get so that the given unit will divide out and leave us with the unit we want. 1800 lb 1 ton 2000 lb 9 lb 1 1800 1 ton 2000 10 lb Divide the numbers by 2000; divide out the unit of pounds. 9 ton 10 Multiply. 9 10 ton or 0.9 ton Simplify. Therefore, 1800 lb 9 10 ton or 0.9 ton. d) Step 1: Identify the units given and the units we want to get. Write down the relationship between those units. We are given 5 2 3 yd and want to convert to feet. The relationship is 1 yd 3 ft Step 2: Multiply the given measurement by the unit fraction relating the unit given and the unit we want to get so that the given unit will divide out and leave us with the unit we want. 5 2 3 yd 3 ft 1 yd 17 3 yd 3 ft 1 yd Change the mixed number to an improper fraction. 17 31 yd 1 3 ft 1 yd Divide out 3; divide out the unit of yards. 17 ft 1 Multiply. 17 ft Simplify. So, 5 2 3 yd 17 ft. YOU TRY 4 Use unit analysis to convert each measurement to the indicated unit. a) 3 lb to ounces b) 9 c to pints c) 48 min to hours d) 2 1 4 mi to feet Sometimes, we have to use more than one unit fraction to convert to the desired unit. This is often done in science classes. 438 CHAPTER 7 Measurement and Conversion www.mhhe.com/messersmith
