A fraction scale is depicts a portion of an object or geographical feature on a map. While a linear scale has equal divisions for equal values.
<h3>What is the fraction scale of 2cm = 30Km?</h3>
1 km = 1000 m, and 1 m = 100 cm.
=> 1 km = 1000 × 100 cm = 100000 cm
=> 10 km = 10 × 100000 cm = 1000000 cm
From the question, 2cm represents 30Km, Hence,
2cm represents 3,000,000 on ground
=> 1 cm represents (3,000,000 / 2) cm on ground
or 1cm represents 1,500,000cm on the ground.
Thus, the The representative fraction of the scale is 1 : 1,500,000.
This means that 1 cm on map represents 1,500,000 cm on ground.
