Day 17: Real-World Money
Preparatory Stage (Grades 3 to 5) Mathematics | Apex Institute of Maths and Sciences
🚀 Level 1: The Quest (The Money Concept)
Welcome, Young Shopper! Have you ever noticed prices like ₹45.50 on a chocolate wrapper? Money and Decimals are best friends! The number before the dot represents Rupees, and the number after the dot represents Paise.
Money Secret:
1 Rupee = 100 Paise
So, 1 Paisa = $ \frac{1}{100} $ of a Rupee = ₹0.01
1 Rupee = 100 Paise
So, 1 Paisa = $ \frac{1}{100} $ of a Rupee = ₹0.01
| Price Tag | Rupees | Paise |
|---|---|---|
| ₹10.25 | 10 | 25 |
| ₹5.05 | 5 | 05 |
⚡ Level 2: Power-Ups (Shopping Methods)
The Decimal Rule: When adding money, always line up the “Dots” (decimal points). If there are no paise, write it as .00.
Example: Add ₹12.50 and ₹7.75
$ 12.50 $
$ + 07.75 $
———-
$ 20.25 $
$ 12.50 $
$ + 07.75 $
———-
$ 20.25 $
