Answer 2

a) 1 centimeter = 10 millimeter

1 meter = 100 centimeter.

And

1 kilometer = 1000 meter

So,

i) 5 cm

5 \:cm=\frac{5}{100}m=0.05m

5 \:cm=\frac{5}{100}m=0.05m=\frac{0.005}{1000}=0.000005\:km

ii) 35 mm

35\:mm=\frac{35}{10}cm=3.5cm

35\:mm=\frac{35}{10}cm=3.5cm=\frac{3.5}{100}m=0.035m

35\:mm=\frac{35}{10}cm=3.5cm=\frac{3.5}{100}m=0.035m=\frac{0.035}{1000}km=0.000035km

b) convert 7 kg 70 g. in kg.

1 kg = 1000 g

7 kg 70 g = 7+

1000

70

=7+0.070

7 kg 70 g . = 7.070 kg
