Geography
Convert the following representative fractions into statements:
(i) 1: 63360 (to show miles).
(ii) 1: 1000000 (to show kilometres).
(iii) 1: 100 (to show metres).
(iv) 1: 10 (to show metres).
(v) 1: 200,000 (to show kilometres).
Answer
(i) R.F. = 1:63360
That means 1 inch on the map = 63360 inches on the ground
The scale is 1 inch to 1 mile
(Since 1 mile = 63,360 inches)
(ii) R.F. = 1:10,00,000
That means 1 cm on the map = 10,00,000 cm on the ground
The scale is 1 cm to 10 km
(Since 1 km = 1,00,000 cm)
(iii) R.F. = 1:100
That means 1 cm on the map = 100 cm on the ground
The scale is 1 cm to 1 m
(Since 100 cm = 1 m)
(iv) R.F. = 1:10
That means 1 cm on the map = 10 cm on the ground
The scale is 10 cm to 1 m
(Since 1 m = 100 cm)
(v) R.F. = 1:2,00,000
That means 1 cm on the map = 2,00,000 cm on the ground
The scale is 1 cm to 2 km
(Since 1 km = 1,00,000 cm)
