Evaluating numbers is necessary to know which quantity is larger and which quantity is smaller.

We all know that, a 2-digit quantity is larger than a 1-digit quantity.

A: Comparability of 2-Digit Numbers:

evaluate two numbers to search out out which is the larger quantity.

**For instance:**

**1. Evaluate the numbers 34 and 43.**

**Technique 1: Utilizing the quantity line**

The quantity that comes in a while the quantity line is the larger quantity. First, evaluate the tens. Then evaluate those.

We all know from the quantity line that 43 comes after 34, so 43 > 34.

**Technique 2:** Utilizing place worth

The quantity with the higher digit within the larger place is the larger quantity. First, evaluate the tens. Then evaluate those.

We begin with the tens place.

Since 4 > 3 within the tens place, 43 > 34.

**2. Evaluate the numbers 7 and 13.**

The quantity with extra variety of digits is all the time higher and

the quantity with much less variety of digits is all the time smaller.

7 is a 1-digit quantity and 13 is a 2-digit quantity. Due to this fact,

7 < 13 or 13 > 7.

**Observe:**

What can we do if each the digits are similar within the tens place?

We evaluate the digits within the ones place.

**3. Evaluate the numbers 35 and 38.**

Utilizing place worth

**Step I:** First evaluate the tens place.

The tens place has the digit 3 in each the numbers.

**Step II: **Then evaluate those place

Those place has 5 within the quantity 35.

Those place has 8 within the quantity 38.

Since 5 < 8 within the ones place, so 35 < 38 or 38 > 35.

B. Comparability of 3-Digit Numbers:

In the identical method a 3-digit quantity is all the time higher than a 2-digit quantity.

The quantity with extra digits is all the time higher than the quantity with much less digits.

Solved examples for evaluating numbers:

**1.** **Allow us to evaluate two numbers 103 and 99.**

**Resolution:**

103 has 3-digits.

99 has 2-digits.

So, 103 is larger than 99.

**2.** **Evaluate the quantity 125 and 87 and discover which quantity is the higher quantity.**

**Resolution:**

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

= 8 tens and 45 ones

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

125 = 8 tens + 45 ones

87 = 8 tens + 7 tens

It’s clear 45 ones > 7 ones

or, 125 ones > 87 ones

or, 125 > 87

Due to this fact, the quantity which has extra digits than the opposite is larger

If the variety of digits are equal, we first evaluate the digits in tons of place. The quantity with higher digit within the tons of place is larger.

**3.** **Allow us to evaluate 369 and 216.**

**Resolution:**

Evaluating the digits within the tons of place we discover that 3 is larger than 2.

So, 369 is larger than 216 and 369 > 216.

**4.** **Allow us to evaluate 468 and 438.**

**Resolution:**

Evaluating the digits within the tons of place we discover that each numbers have similar digit.

Subsequent, we evaluate the digits in tens place. We discover that 6 > 3.

So, 468 > 438

**5.** **Allow us to evaluate 822 and 829.**

**Resolution:**

Evaluating the digits within the tons of and tens place we discover that they’re similar in each the numbers.

So, we evaluate the digits in ones place. We discover that 9 > 2.

So, 829 > 822.

**6.** **Evaluate 238
and 148.**

**Resolution:**

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’s clear 238 ones > 148 ones.

Therefore, 238 > 148 and 148 < 238

Each 238 and 148 have the identical variety of digits however the

digit at tons of place in 238 has larger place worth (200) than the digit at

tons of place worth in 148 i.e., (100) or 2 > 1.

Due to this fact, 238 > 148

**7.** **Evaluate the
following numbers:**

**(i)** 256 and 234

**Resolution:**

2 tons of + 5 tens + 6 ones = 200 + 50 + 6 = 256 ones

2 tons of +3 tens + 4 ones =200 + 30 + 4 = 234 ones

256 ones > 234 ones

or, 256 > 234

Each the quantity have equal variety of tons of, however 256 has

extra tens 234

Due to this fact, 256 > 234

**(ii)** 182 and 186

**Resolution:**

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

Each the numbers have equal variety of tons of and equal

variety of tens. However 182 has much less ones than 186.

Due to this fact, 182 < 186

**Notes for evaluating numbers:**

(i) The quantity having extra hundred is larger

(ii) If the quantity has equal tons of as the opposite quantity,

however higher tens than the opposite, it’s higher.

(iii) If one quantity has equal tons of and equal tens however

extra ones than the opposite, it’s higher.
