Describe how you decided which number is the bigger one. Which position (Th, H, T, O) helped you to decide this?
Answer:
To compare the numbers 3012 and 3102, look at each place value starting from the left
First Thousands (Th) place is the same in both numbers that is 3=3
Next, we check the Hundreds (H) place.
In 3012, the Hundreds digit is 0.
In 3102, the Hundreds digit is 1.
Since, 1>0 so the number 3102 is bigger than 3012.
Hence, the Hundreds (H) place helped to decide which number is bigger.

∴ 2190<2910
(b) In 1009 and 9001, the thousands digit in 1009 is less than the thousands digit in 2910.
∴ 1009<9001

Question 28.
Use the signs <, =, > to compare the following.
(i) 2 Tens + 4 Thousands + 3 Hundreds …….. 2043
(ii) 2 Tens + 4 Thousands + 3 Hundreds ………. 4320
(iii) 2 Thousands +9 Hundreds +9 Tens + 9 Ones ………….. 3000
(iv) 15 Ones +9 Tens + 3 Hundreds ………. 1593
(v) 5000+30+4 ……………… 5034
(vi) 5000+300+4 ……………… 5340
Answer:
(i) 2 tens +4 thousands +3 hundreds
=20+4000+300=4320
In 4320 and 2043, the thousands digit in 4320 is greater than the thousands digit in 2043.
∴ 4320>2043
(ii) 2 tens +4 thousands +3 hundreds
= 20+4000+300=4320
In 4320 and 4320, the thousands, hundreds, tens and ones digits are same.
∴ 4320=4320
(iii) 2 thousand +9 hundreds +9 tens +9 ones
=2000+900+90+9=2999
In 2999 and 3000, the thousands digit in 2999 is less than the thousands digit in 3000
∴ 2999<3000
(iv) 15 ones +9 tens +3 hundreds
= 1 ten +5 ones +9 tens +3 hundreds
= 5 ones +10 tens +3 hundreds
= 5 ones +1 hundred +3 hundreds
= 4 hundreds +5 ones
= 400+5=405
In 405 and 1593, 4 hundred is always less than the one thousand.
∴ 405<1593
(v) 5000+30+4=5034
In 5034 and 5034, all the digits (thousands, hundreds, tens and ones) are same.
∴ 5034=5034
(vi) 5000+300+4=5304
In 5304 and 5340, the thousands and hundreds digits are same but tens digit in 5304 is less than tens digit in 5340.
∴ 5304<5340
Question 29.

Answer:
(i) 7543 < 7680
(ii) 8530 < 8631
(iii) 5231 < 5325
