Name___________________ DSPM 0700 HOMEWORK (ASSIGNMENT 8, SECTIONS 4-1 AND 4-3) Change to the following: 1. 23 dkm = __________________ mm To change from one metric unit to the other, use the “place value chart.” kilo- k 1,000 hecto- h 100 deka- dk 10 standard unit (no abbreviation) 1 deci- d 0.1 centi- c 0.01 milli- m 0.001 Find the prefix of the unit you are changing from. Count the number of places from the original unit to the new unit and note which direction to move the decimal point (smaller to larger = move left; larger to smaller = move right). dkm to mm = 4 places right 23 dkm = 230,000 mm 2. 2,847 g = __________________ kg g to kg = 3 places left 2,847 g = 2.847 kg 3. 15.4 dL = ___________________ dkL dL to dkL = 2 places left 15.4 dL = 0.154 dkL 4. 3,000,974 cg = ________________ kg cg to kg = 5 places left 3,000,974 cg = 30.00974 kg 5. 3,785 mL = ___________________ L mL to L = 3 places left 3,785 mL = 3.785 L Perform the following operations: 6. 15 kg 400 g For metric units, you can change from the smaller unit to the larger or the larger unit to the smaller. 15 kg 400 g 15,000 g 400 g 14,600 g     15 kg 400 g 15 kg 0.4 kg 14.6 kg     7. 4 km + 17 hm 4 km + 17 hm 40 hm 17 hm 57 hm    4 km 17 hm 4 km 1.7 km 5.7 km     8. 4.5 km 3.5 Multiplying a measure by a number results in a measure. 4.5 km 3.5 15.75 km  This is equivalent to “What is the total length of 3.5 measurements of 4.5 km each?” 9. 5 kg 20 g Dividing a measure by a measure results in a number. You must change the units to a common unit. 5,000 g5 kg 20 g  20 g 250 5 kg5 kg 20 g  0.02 kg 250 The answer is 250 units, which is equivalent to “How many 20-g packages can be made from 5 kg?”
