How is Money Represented Visually and Numerically?
The concept of Representation Of Money is a foundational topic in both mathematics and daily life. Understanding how money is visually, numerically, and symbolically represented is essential for school exams, competitive tests, and practical situations like shopping or budgeting. Mastering this topic helps students make sense of real-world numerical problems with ease.
Understanding the Representation Of Money
The representation of money refers to the different ways in which money is shown, counted, and used in mathematics and everyday transactions. This includes physical forms like coins and notes, numerical forms using numbers and decimals, and symbols such as ₹ (Rupee), $ (Dollar), or £ (Pound). Recognizing these forms is important for calculation, identification, and comparison of currency values.
Money is represented in two main ways:
- Physical representation: Coins and notes of different values, colors, sizes, and shapes.
- Numerical/Mathematical representation: Writing amounts using digits, decimal points, and currency symbols (for example, ₹45.75 or Rs. 45.75).
At Vedantu, we simplify concepts like the physical and visual representation of money, helping students identify denominations and understand calculations confidently.
Forms and Symbols of Money
Money takes various forms, each with its own way of being represented:

| Coins |
₹1, ₹2, ₹5, ₹10 coins 1¢, 5¢, 10¢ (US) |
By value engraved on the coin, color, size, and shape |
| Notes |
₹10, ₹20, ₹50, ₹100, ₹200, ₹500, ₹2000 $1, $2, $5, $10 (US) |
Printed number, color, unique features |
| Numbers (Digits & Decimals) |
₹237.50 Rs. 100.25 |
Using digits and decimal points to show rupees and paise (or dollars and cents) |
| Words |
“Fifty rupees” “One hundred and twenty-five rupees and fifty paise” |
Amount spelled out in English or another language |
| Symbols | ₹, Rs., $, £, ¥ | Currency symbols used before or after the amount |
Visual Representation: Notes, Coins and Their Denominations
Visual features play an important role in the visual representation of money. Each denomination of currency note or coin has a unique color, size, and image, making them easy to identify.
- ₹1 Coin – Smallest, usually silver or steel color.
- ₹5 Coin – Larger, bimetallic or silver.
- ₹20 Note – Yellow/brown color, medium size.
- ₹100 Note – Purple, larger size compared to ₹10 or ₹20.

Numerical Representation and Conversion
In mathematics and daily life, money is usually represented numerically using numbers and decimal notation. In India, 1 rupee is equal to 100 paise.
| Representation | Example | Explanation |
|---|---|---|
| Numbers Only | ₹38.75 | 38 rupees and 75 paise (38 x 1 rupee + 75 paise) |
| Words | “Thirty-eight rupees seventy-five paise” | Same amount written in words |
| Paise Only | 3875 paise | ₹38.75 = 38 rupees x 100 + 75 = 3875 paise |
Steps for Rupees–Paise Conversion
- To convert rupees to paise: Multiply by 100.
(E.g., ₹5 = 5 × 100 = 500 paise) - To convert paise to rupees: Divide by 100.
(E.g., 250 paise = 250 ÷ 100 = ₹2.50)

Worked Examples
Let’s practice representing and converting money:
-
Write ₹17 rupees 35 paise in numbers.
Step 1: Write rupees and paise side by side with a decimal.
Step 2: ₹17 rupees 35 paise = ₹17.35 -
Convert ₹8.50 to paise.
Step 1: Multiply rupees by 100: 8 × 100 = 800
Step 2: Add 50 paise: 800 + 50 = 850 paise -
Express 425 paise in rupees.
Step 1: Divide by 100: 425 ÷ 100 = ₹4.25

- How do you represent Rs. 56.25 in words?
- If you have two ₹10 notes and three ₹5 coins, what is your total in rupees?
Common Mistakes to Avoid
- Confusing rupees with paise and writing amounts incorrectly (e.g., writing 8.50 as 850 rupees instead of ₹8.50).
- Missing or misplacing the decimal point when writing money (e.g., Rs12.5 for Rs. 12.05).
- Forgetting that 1 rupee = 100 paise in conversions.
- Ignoring currency symbols (such as ₹ or Rs.) when writing money values.
- Mixing up coins and notes by color or size alone—always check the value printed.
