Large Numbers in Practice

Large Numbers can be shown using the place value. It goes in the thrusting order as shown below

centimeter( cm) in used as a unit of dimension of length. We can use this unit for measuring the length of a pen, the range of a book or note booket. but this unit is too big to measure the consistence of a pen. So, we use another unit named as millimeter( mm). Also, centimeter and millimeter are veritably small units to measure the length of the wall or a room. We use another unit named as meter for the same. Indeed meter is too small unit when we state the distances between two municipalities or metropolises. For this we need kilometers( km).

The relations between units are

1 kilometer = 1000 meters( m)

1 meter = 100 centimeters( cm)

1 centimeter = 10 millimeters( mm)

Also, we have

100 cm = 1 m = 10mm × 100 = 1000 mm

 1000 m  = 1Km = 1000 × 100 cm = 100000 cm

100000 cm =1 km = 100000 × 10 mm = 1000000 mm

10 Million =  1 crore

 1 million =  10 lakhs

(100,000) Hundred Thousands =  1 lakh

 (10,000)Ten Thousands = Thousands Hundreds (1000,000)

 We borrow the following rules to compare two large figures

 Rule- 1 The number with further integers is lesser than the number with lower integers.

 Rule- 2 When two figures have the same number of integers, compare the integers at the leftmost places. The number with the lesser number is lesser. If the integers at the leftmost places are the same also compare the coming integers and so on.
