To find the numbers from their expanded forms, we will evaluate each part step by step.
### Part a:
**Expanded Form:** `2 x 10,00,000 + 3 x 1,00,000 + 5 x 10,000 + 7 x 10`
1. **Calculate each term:**
- \(2 \times 10,00,000 = 20,00,000\) (20 lakhs)
- \(3 \times 1,00,000 = 3,00,000\) (3 lakhs)
- \(5 \times 10,000 = 50,000\) (50 thousand)
- \(7 \times 10 = 70\) (70)
2. **Add the calculated values together:**
- \(20,00,000 + 3,00,000 + 50,000 + 70\)
3. **Perform the addition:**
- \(20,00,000 + 3,00,000 = 23,00,000\)
- \(23,00,000 + 50,000 = 23,50,000\)
- \(23,50,000 + 70 = 23,50,070\)
**Final Number:** 23,50,070
### Part b:
**Expanded Form:** `4 x 1,00,00,000 + 5 x 1,00,000 + 6 x 10,000 + 5`
1. **Calculate each term:**
- \(4 \times 1,00,00,000 = 4,00,00,000\) (4 crores)
- \(5 \times 1,00,000 = 5,00,000\) (5 lakhs)
- \(6 \times 10,000 = 60,000\) (60 thousand)
- \(5 = 5\)
2. **Add the calculated values together:**
- \(4,00,00,000 + 5,00,000 + 60,000 + 5\)
3. **Perform the addition:**
- \(4,00,00,000 + 5,00,000 = 4,05,00,000\)
- \(4,05,00,000 + 60,000 = 4,05,60,000\)
- \(4,05,60,000 + 5 = 4,05,60,005\)
**Final Number:** 4,05,60,005
### Part c:
**Expanded Form:** `7 x 10,00,00,000 + 5 x 1,00,00,000 + 1 x 10,000 + 2 x 1,000 + 9`
1. **Calculate each term:**
- \(7 \times 10,00,00,000 = 70,00,00,000\) (70 crores)
- \(5 \times 1,00,00,000 = 5,00,00,000\) (5 crores)
- \(1 \times 10,000 = 10,000\) (10 thousand)
- \(2 \times 1,000 = 2,000\) (2 thousand)
- \(9 = 9\)
2. **Add the calculated values together:**
- \(70,00,00,000 + 5,00,00,000 + 10,000 + 2,000 + 9\)
3. **Perform the addition:**
- \(70,00,00,000 + 5,00,00,000 = 75,00,00,000\)
- \(75,00,00,000 + 10,000 = 75,00,10,000\)
- \(75,00,10,000 + 2,000 = 75,00,12,000\)
- \(75,00,12,000 + 9 = 75,00,12,009\)
**Final Number:** 75,00,12,009
### Summary of Final Answers:
- a. 23,50,070
- b. 4,05,60,005
- c. 75,00,12,009
