Answer key · Set B
Same Amount, New Unit
1700 1 becomes 7 by multiplying by 7. Do the same to 100: 700.
280 The crayon is 8 cm. 8 × 10 = 80 mm.
348 3 × 16 = 48.
41 L = 1000 mL There are 1000 milliliters in 1 liter.
5True 4 × 100 = 400, so 4 m is 400 cm.
66 100 becomes 600 by multiplying by 6. 1 × 6 = 6 m.
71-B, 2-A, 3-D, 4-C Use the fact: 1 m = 100 cm, 1 kg = 1000 g, 1 cm = 10 mm, 1 km = 1000 m.
87.5 90 ÷ 12 = 7.5.
92 1 minute is 60 seconds. 60 becomes 1 by dividing by 60, so 120 ÷ 60 = 2.
10210 1 hour is 60 minutes. 3.5 × 60 = 210.
11cm The meters cancel, because one is on top and one is on the bottom. Centimeters are left.
12250 2.5 × 100 = 250.
