Answer 3

Sure, I can help you with these calculations. Here are the step-by-step solutions for each multiplication problem:

1) 207 * 503: - Multiply the ones place: 7 * 3 = 21. Write down the 1 and carry over the 2. - Multiply the tens place: 0 * 3 = 0. Write down the 0. - Multiply the hundreds place: 2 * 3 = 6. Write down the 6. - Multiply the ones place: 7 * 5 = 35. Write down the 5 and carry over the 3. - Multiply the tens place: 0 * 5 = 0. Write down the 0. - Multiply the hundreds place: 2 * 5 = 10. Write down the 10. - Multiply the thousands place: 2 * 5 = 10. Write down the 10. - Add up all the partial products: 0 + 0 + 6 + 0 + 35 + 10 + 10 = 61,050.

Therefore, 207 * 503 = 61,050.

2) 609 * 305: - Multiply the ones place: 9 * 5 = 45. Write down the 5 and carry over the 4. - Multiply the tens place: 0 * 5 = 0. Write down the 0. - Multiply the hundreds place: 6 * 5 = 30. Write down the 30. - Multiply the ones place: 9 * 0 = 0. Write down the 0. - Multiply the tens place: 0 * 0 = 0. Write down the 0. - Multiply the hundreds place: 6 * 0 = 0. Write down the 0. - Multiply the thousands place: 6 * 3 = 18. Write down the 18. - Add up all the partial products: 0 + 0 + 30 + 0 + 0 + 0 + 18 = 48,450.

Therefore, 609 * 305 = 48,450.

3) 708 * 504: - Multiply the ones place: 8 * 4 = 32. Write down the 2 and carry over the 3. - Multiply the tens place: 0 * 4 = 0. Write down the 0. - Multiply the hundreds place: 7 * 4 = 28. Write down the 28. - Multiply the ones place: 8 * 0 = 0. Write down the 0. - Multiply the tens place: 0 * 0 = 0. Write down the 0. - Multiply the hundreds place: 7 * 0 = 0. Write down the 0. - Multiply the thousands place: 7 * 5 = 35. Write down the 35. - Add up all the partial products: 0 + 0 + 28 + 0 + 0 + 0 + 35 = 63,420.

Therefore, 708 * 504 = 63,420.

4) 909 * 808: - Multiply the ones place: 9 * 8 = 72. Write down the 2 and carry over the 7. - Multiply the tens place: 0 * 8 = 0. Write down the 0. - Multiply the hundreds place: 9 * 8 = 72. Write down the 72. - Multiply the ones place: 9 * 0 = 0. Write down the 0. - Multiply the tens place: 0 * 0 = 0. Write down the 0. - Multiply the hundreds place: 9 * 0 = 0. Write down the 0. - Multiply the thousands place: 9 * 8 = 72. Write down the 72. - Add up all the partial products: 0 + 0 + 72 + 0 + 0 + 0 + 72 = 65,472.

Therefore, 909 * 808 = 65,472.

I hope this helps! Let me know if you have any further questions.
