What is it?

A comparison statement tells us how two or more things are similar or different. It helps us understand which one is bigger, smaller, equal, or has more/less of something. We use special words and symbols like 'greater than', 'less than', or 'equal to' to make these statements.

Simple Example

Quick Example

Imagine your friend scored 85 marks in Science and you scored 90 marks. A comparison statement would be: 'My score (90) is greater than my friend's score (85).' This clearly shows who scored more.

Worked Example

Step-by-Step

Let's compare the price of two cricket bats.
--- Step 1: Identify the items to compare. Bat A costs Rs. 1500. Bat B costs Rs. 1200.
--- Step 2: Decide what aspect you are comparing. Here, we are comparing their prices.
--- Step 3: Use a comparison word or symbol. Is Bat A's price greater than, less than, or equal to Bat B's price?
--- Step 4: Write the comparison statement. Rs. 1500 is greater than Rs. 1200.
--- Step 5: You can also use symbols: 1500 > 1200.
--- Answer: Bat A is more expensive than Bat B.

Why It Matters

Comparison statements are super important in many fields! Scientists use them to compare experimental results, engineers compare different designs, and doctors compare patient data. Even finance experts use them to compare investments, helping them make smart decisions for the future.

Common Mistakes

MISTAKE: Confusing 'greater than' and 'less than' symbols. For example, writing 5 < 3 instead of 5 > 3. | CORRECTION: Remember the 'alligator mouth' always eats the bigger number. So, the open side of the symbol always faces the larger value.

MISTAKE: Not comparing the same units. For example, comparing 5 kg to 500 grams directly without converting. | CORRECTION: Always make sure the items you are comparing are in the same units (e.g., both in kg, both in rupees, both in cm) before making a comparison.

MISTAKE: Forgetting to include the items being compared in the statement, just giving the symbol. For example, just writing '>'. | CORRECTION: Always state what you are comparing on both sides of the symbol or in your sentence, like '10 apples > 5 apples' or 'The blue car is faster than the red car'.

15 + 5 = 20

99 = 100

The Correct Answer Is:

Option C (15 + 5 = 20) correctly states that the value on the left side is equal to the value on the right side. Options A, B, and D use symbols incorrectly or state false equalities.

Real World Connection

In the Real World

When you compare mobile data plans from different companies like Jio and Airtel, you are using comparison statements. You might compare which plan offers 'more GB per day' or which one is 'less expensive' for a month. This helps you choose the best plan for your needs.
