Question 3 (ii)
Express 35 mm in cm, m and km

Answer 1

$\text{Express 35 mm in cm, m and km.}10mm=1cm\therefore 1mm=\frac{1}{10}cm\Rightarrow 35mm=\frac{35}{10}=3.5cmNow,100cm=1meter\therefore 1cm=\frac{1}{100}meter\Rightarrow 3.5cm=\frac{3.5}{100}=0.035meterAgain1000meters=1kilometers\therefore 1meter=\frac{1}{1000}kilometer\Rightarrow 0.035meter=\frac{0.035}{1000}=0.000035kilometer$
