a)50m to 20 km

:- 1km=1000m

so 20km=20×1000 m

=20000m

ratio:- 50m/20000m

=5/2000

=1/400

= 1:400

b)Rs 450 to 500p

:- 1 rupees=100 paise

so 450rupees=450×100 paise

=45000paise

ratio:-45000p/500p

=450/5

=90/1

=90:1

c)200ml to 1 litre

:-1 litre=1000ml

ratio:-200ml/1000ml

=2/10

=1/5

=1:5
