Worksheet 1: Writing Rupees and Paise Using a Dot
Basic Concept: $mathbf{₹ 1 = 100 text{ paise}}$.
The dot (.) separates rupees from paise. The number on the left of the dot represents Rupees and the two digits on the right represent Paise.
| Rupees and Paise in Words | Notation in Figures | Important Caution / Note |
|---|---|---|
| Fifty-five rupees seventy-five paise | ₹ 55.75 | Standard 2-digit paise |
| Eight rupees five paise | ₹ 8.05 | Write 05 for 5 paise (₹ 8.50 would mean 50 paise!) |
| Sixty rupees | ₹ 60.00 | Two zeros indicate 0 paise |
| Seventy-five paise only | ₹ 0.75 | 0 in rupees place |
| One hundred twenty rupees fifty paise | ₹ 120.50 | Standard notation |
Worksheet 2: Conversion of Money
1. Converting Rupees into Paise: Multiply by 100 (or simply remove the symbol ₹ and dot, and write ‘p’):
- (a) $₹ 7 = 7 times 100 = mathbf{700text{ p}}$
- (b) $₹ 18.25 = mathbf{1825text{ p}}$
- (c) $₹ 9.05 = mathbf{905text{ p}}$
- (d) $₹ 42.50 = mathbf{4250text{ p}}$
- (e) $₹ 0.85 = mathbf{85text{ p}}$
2. Converting Paise into Rupees: Count 2 digits from the right end and place a dot (.) with the ₹ symbol:
- (a) $650text{ p} = mathbf{₹ 6.50}$
- (b) $4075text{ p} = mathbf{₹ 40.75}$
- (c) $805text{ p} = mathbf{₹ 8.05}$
- (d) $900text{ p} = mathbf{₹ 9.00}$
- (e) $75text{ p} = mathbf{₹ 0.75}$
