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

a. 74 km

b.  .0246g

c. = .049 kg

d.  8400mm

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

A.

we know that, 1km=1000m

B.

we know that, 1000000μg=1g

C.

we know that, 1000000000μg=1kg

D.

we know that ,100mm=1dm

the answer is b ) square root of 5

the answer would be a
