Question

3, Express in m, dm, cm and mm. (b) 2.426 m (a) 131.112 m (e) 0.603 m () 854.025 m​

Answer 1

Points to be remembered...

m = meter,
dm = decimeter,  {1m =  $10^-^1=\frac{1}{10} = 0.1dm$}
cm = centimeter, {1m = $10^-^2=\frac{1}{100} = 0.01cm$}
mm = millimeter {1m =$10^-^3=\frac{1}{1000} =0.001mm$ }

Solution :-

a)  2.426m

$2.426*\frac{1}{10} = 0.2426dm\\\\2.426*\frac{1}{100}=0.02426cm\\\\2.426*\frac{1}{1000}=0.002426mm$

b) 131.112

$131.112*\frac{1}{10} =13.1112dm\\\\131.112*\frac{1}{100} =1.31112cm\\\\131.112*\frac{1}{1000} =0.131112mm$

c) 0.603m

$0.603*\frac{1}{10}=0.0603dm=0.603*10^-^1dm\\\\0.603*\frac{1}{100}=0.00603cm=0.603*10^-^2cm\\\\0.603*\frac{1}{1000}=0.000603cm=0.603*10^-^3mm$

d) 854.025m

$854.025*\frac{1}{10}=85.4025dm\\\\854.025*\frac{1}{100}=8.54025cm\\\\854.025*\frac{1}{1000}=0.854025dm$
