Area of North America = 17 sq.units
Area of Europe = 10 sq.units
Area of South America = 18 sq.units
Area of Africa = 26 sq.units
Area of Asia = 44 sq.units
Area of Australia = 8 sq.units
Area of Antarctica = 13 sq.units
(a) Ratio of area of Africa to Europe = `26/10`
= `13/5` .....[On dividing numerator and denominator by 2]
= 13:5
(b) Ratio of area of Australia to Asia = `8/44`
= `2/11` .....[On dividing numerator and denominator by 4]
= 2:11
(c) Ratio of Antarctica to combined area of North America and South America = `13/(17 + 18)`
= `13/35`
