Question

b) 5 yd = ___ ft
c) 2.7 mi = ___ yd
e) 5.21 g = ___ mg
h) 3085 mg = ___ g
f) 0.315 kl = ___ ml
i) 987 cl = ___ dal
b) 42307 cg = 0.42307 kg

Explanation:

Step1: Recall conversion factors

1 yard (yd) = 3 feet (ft), 1 mile (mi)= 1760 yards (yd), 1 gram (g)= 1000 milligrams (mg), 1 kilogram (kg) = 100000 centigrams (cg), 1 liter (L)=1000 milliliters (mL), 1 decaliter (dal)= 100 centiliters (cl)

Step2: Solve part b

Since 1 yd = 3 ft, then 5 yd=5×3 ft = 15 ft

Step3: Solve part c

Since 1 mi = 1760 yd, then 2.7 mi=2.7×1760 yd = 4752 yd

Step4: Solve part e

Since 1 g = 1000 mg, then 5.21 g=5.21×1000 mg = 5210 mg

Step5: Solve part f

Since 1 kL = 1000000 mL, then 0.315 kL=0.315×1000000 mL = 315000 mL

Step6: Solve part h

Since 1 g = 1000 mg, then 3085 mg=3085÷1000 g = 3.085 g

Step7: Solve part i

Since 1 dal = 100 cl, then 987 cl=987÷100 dal = 9.87 dal

Answer:

b) 15 ft
c) 4752 yd
e) 5210 mg
f) 315000 mL
h) 3.085 g
i) 9.87 dal
