Question

1. express 5 cm in metre and kilometre
2. express 35 mm in cm, m and km
3. express in kg:
a) 200 g b) 3470 g c) 4 kg 8 g

please help me with these questions

Answer 1

1.Converting into metre (1m=100cm)= 5/100=0.05m.. Converting into km. (1km=100000cm). so 5 cm=5/100000=0.00005km.

2.Here, we are asked to express 35 mm in cm, m and km. We know that, 1mm=110cm . So, 35mm=35100cm=3.5cm . Now, we have 35 mm = 3.5 cm.

3.a)0.200kg

b) 3.470kg

c) 4008kg

Answer 2

1. 5cm in meter : 5/100 = 0.05 m

5cm into kilometer : 5/100*1000 = 0.00005 km

3. 1 kg = 1000 grams

so ,

a) 200 g = 0.2 kg

b) 3470 g = 3.47 kg

c) 4 kg 8 g = 4.008 kg
