Ncert Solutions for Class 6 Maths Chapter 1 Knowing Our Numbers Exercise 1.3 Tips:-
Revisiting place value:
You have done this quite earlier, and you will certainly remember the expansion
of a 2-digit number like 78 as
78 = 70 + 8 = 7 × 10 + 8
Similarly, you will remember the expansion of a 3-digit number like 278 as
278 = 200 + 70 + 8 = 2 × 100 + 7 × 10 + 8
We say, here, 8 is at ones place, 7 is at tens place and 2 at hundreds place.
Later on we extended this idea to 4-digit numbers.
For example, the expansion of 5278 is
5278 = 5000 + 200 + 70 + 8
= 5 × 1000 + 2 × 100 + 7 × 10 + 8
Here, 8 is at ones place, 7 is at tens place, 2 is at hundreds place and 5 is at
thousands place.
With the number 10000 known to us, we may extend the idea further. We
may write 5-digit numbers like
45278 = 4 × 10000 + 5 × 1000 + 2 × 100 + 7 × 10 + 8
We say that here 8 is at ones place, 7 at tens place, 2 at hundreds place,
5 at thousands place and 4 at ten thousands place. The number is read as forty
five thousand, two hundred seventy eight. Can you now write the smallest
and the greatest 5-digit numbers?
An aid in reading and writing large numbers:-
Try reading the following numbers :
(a) 279453 (b) 5035472
(c) 152700375 (d) 40350894
Was it difficult?
Did you find it difficult to keep track?
Sometimes it helps to use indicators to read and write large numbers.
Shagufta uses indicators which help her to read and write large numbers.
Her indicators are also useful in writing the expansion of numbers. For example,
she identifies the digits in ones place, tens place and hundreds place in 257 by
writing them under the tables O, T and H as
H T O Expansion
2 5 7 2 × 100 + 5 × 10 + 7 × 1
Similarly, for 2902,
Th H T O Expansion
2 9 0 2 2 × 1000 + 9 × 100 + 0 × 10 + 2 × 1
