Question

1. How many cm are equal to 1.45 m?

Answer 1

Explanation:

(1) 1 m = 100 cm

1.45 m = 100 × 1.45 cm = 145 cm

(2) 1 kg = 1000 g

325 g = 0.325 kg

(3) 1 L = 1000 mL

0.0024 L= 2.4 mL

(4) 1 km = 1000 m

$1.55\times 10^4\ m=1.55\times 10^4\times 0.001=15.5\ km$

(5) 1 mm = 0.001 m

$4.75\times 10^{-2}\ m=4.75\times 10^{-2}\times 1000\ mm\\\\=47.5\ mm$

(6) 1 kg = 100000 cg

0.459 kg = 45900 cg

(7) 1 dm = 10⁻⁴ dm

5,995 dm = 5,995 × 10⁻⁴ km

(8) 1 g = 1000 mg

450 g = 450000 mg

(9) 1 dm = 100 m

0.003 dm = 0.3 mm

(10) 1 mL = 0.001 l

4.567 × 10⁴ mL = 45.67 L
