Comparing Numbers

Comparing numbers is important to know which number is greater and which number is smaller.

Solved examples for comparing numbers:

1. Compare the number 125 and 87 and find which number is the greater number.

Solution:

1 hundred 2 tens 5 ones                         =      125      =       12 tens and 5 ones

                                                                            =         8 tens and 45ones

8 tens 7 ones                                      =        87       =         8 tens and 7 ones

125 = 8 tens + 45 ones                   

87 = 8 tens + 7 tens          

It is clear 45 ones > 7 ones 

or, 125 ones > 87 ones           

or, 125 > 87

Therefore, the number which has more digits than the other is greater


2. Compare 238 and 148.

Solution:

2 hundred 3 tens 8 ones    = 238   = 200 + 30 + 8

1 hundred 4 tens 8 ones    = 148   = 100 + 40 + 8

238 = 200 + 30 + 8 = 238 ones

148 = 100 + 40 + 8 =148 ones

It is clear 238 ones > 148 ones.

Hence, 238 > 148 and 148 < 238

Both 238 and 148 have the same number of digits but the digit at hundreds place in 238 has higher place value (200) than the digit at hundreds place value in 148 i.e., (100) or 2 > 1.

Therefore, 238 > 148


3. Compare the following numbers:

(i) 256 and 234

Solution:

2 hundreds + 5 tens + 6 ones = 200 + 50 + 6 = 256 ones

2 hundreds +3 tens + 4 ones =200 + 30 + 4 = 234 ones

256 ones > 234 ones

or, 256 > 234

Both the number have equal number of hundreds, but 256 has more tens 234

Therefore, 256 > 234

(ii) 182 and 186

Solution:

1 hundred + 8 tens + 2 ones    = 100 + 80 + 2 = 182 ones                         

1 hundred + 8 tens + 6 ones = 100 + 80 + 6 = 186 ones

or, 182 < 186

Both the numbers have equal number of hundreds and equal number of tens. But 182 has less ones than 186.

Therefore, 182 < 186

Notes for comparing numbers:

(i) The number having more hundred is greater

(ii) If the number has equal hundreds as the other number, but greater tens than the other, it is greater.

(iii) If one number has equal hundreds and equal tens but more ones than the other, it is greater.
