Question
In the given figure, the comparative areas of the continents are given: What is the ratio of the areas of
(a) Africa to Europe
(b) Australia to Asia
(c) Antarctica to Combined area of North America and South America.
Solution
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`
= 13:35
