What is 456 - 47?

A. 414
B. 409
C. 408
D. 4149

Answer 1

To solve 456 - 47, subtract the numbers step by step: 6 - 7 = -1, borrow 1 from the tens place (15 - 4 = 11), and subtract the hundreds place (4-0 = 4). The result is 409 (option B).

Step-by-step explanation:

To solve the equation 456 - 47, we subtract the numbers step by step:

1. Start with the ones place: 6 - 7 = -1
2. Since we cannot have a negative number in the ones place, we borrow 1 from the tens place. So, the tens place becomes 15 - 4 = 11
3. Finally, subtract the hundreds place: 4 - 0 = 4

Thus, 456 - 47 = 409 (option B).
