Answer 1

Explanation:

a) 76.2 dm = 76.2 * 100 = 7620 mm

b) 2.1 km = 2.1 *100000 = 210000

c) 0.123 Kg = 0.123 * 1000 = 123 g

d) 2.278*10¹¹ km = 2.278*10¹¹ * 10⁵ = 2.278* 10¹¹⁺⁶ = 2.278*10¹⁷ cm

e) 500 nm = 5*10⁻¹⁰ km

f) 35 mm = 35÷ 1000 = 0.035 m

g) 450 cm = 450 *10 = 4500 mm

h) 250 km = 250 * 100000 = 25000000 cm

i) 1500 micro gram = 0.0015 g
