Question

Perform the following conversions.

a. 0.074 km to m
b. 24,600 μg to g
c. 4.9 × 107 μg to kg
d. 84 dm to mm

Answer 1

Answer:-

A.

we know that, 1km=1000m

• 0.074km=0.74×1000/1
• 0.074km=74m.

B.

we know that, 1000000μg=1g

• 24,600μg=24600×1/1000000
• 24,600μg=0.0246g

C.

we know that, 1000000000μg=1kg

• 4.9 ×10^7 μg=4.9×10000000×1/1000000000
• 4.9×10^7μg=49000000×1/1000000000
• 4.9 × 107 μg=0.49Kg.

D.

we know that ,100mm=1dm

• 84dm=84×100
• 84dm=8400mm

Answer 2

a. 74 km

b. .0246g

c. = .049 kg

d. 8400mm

Step-by-step explanation:

a. 0.074 km to m

1000 meters is 1 km

.074 km* 1000m /1 km = 74 km

b. 24,600 μg to g

10^6 ug is 1 gram

24600 ug * 1 g/ 1000000 ug = .0246g

c. 4.9 × 10^7 μg to kg

4.9 × 10^7 μg* 1 g/ 1000000 ug * 1kg/1000g = .049kg

d. 84 dm to mm

84 dm * 100 mm/ 1dm = 8400mm
