Problem: Solve the subtraction problems (3-Digits, No Regrouping)
The task involves solving nine 3-digit subtraction problems where no regrouping is required. This means that in each column (ones, tens, hundreds), the top digit is greater than or equal to the bottom digit, so we can subtract directly without borrowing.
#### Step-by-Step Solutions:
1.
747 - 115
- Ones place: \( 7 - 5 = 2 \)
- Tens place: \( 4 - 1 = 3 \)
- Hundreds place: \( 7 - 1 = 6 \)
- Result: \( 747 - 115 = 632 \)
2.
509 - 301
- Ones place: \( 9 - 1 = 8 \)
- Tens place: \( 0 - 0 = 0 \)
- Hundreds place: \( 5 - 3 = 2 \)
- Result: \( 509 - 301 = 208 \)
3.
773 - 142
- Ones place: \( 3 - 2 = 1 \)
- Tens place: \( 7 - 4 = 3 \)
- Hundreds place: \( 7 - 1 = 6 \)
- Result: \( 773 - 142 = 631 \)
4.
578 - 427
- Ones place: \( 8 - 7 = 1 \)
- Tens place: \( 7 - 2 = 5 \)
- Hundreds place: \( 5 - 4 = 1 \)
- Result: \( 578 - 427 = 151 \)
5.
759 - 448
- Ones place: \( 9 - 8 = 1 \)
- Tens place: \( 5 - 4 = 1 \)
- Hundreds place: \( 7 - 4 = 3 \)
- Result: \( 759 - 448 = 311 \)
6.
888 - 184
- Ones place: \( 8 - 4 = 4 \)
- Tens place: \( 8 - 8 = 0 \)
- Hundreds place: \( 8 - 1 = 7 \)
- Result: \( 888 - 184 = 704 \)
7.
542 - 322
- Ones place: \( 2 - 2 = 0 \)
- Tens place: \( 4 - 2 = 2 \)
- Hundreds place: \( 5 - 3 = 2 \)
- Result: \( 542 - 322 = 220 \)
8.
896 - 514
- Ones place: \( 6 - 4 = 2 \)
- Tens place: \( 9 - 1 = 8 \)
- Hundreds place: \( 8 - 5 = 3 \)
- Result: \( 896 - 514 = 382 \)
9.
436 - 106
- Ones place: \( 6 - 6 = 0 \)
- Tens place: \( 3 - 0 = 3 \)
- Hundreds place: \( 4 - 1 = 3 \)
- Result: \( 436 - 106 = 330 \)
Final Answers:
\[
\boxed{
\begin{array}{ccc}
1. & 632 & \\
2. & 208 & \\
3. & 631 & \\
4. & 151 & \\
5. & 311 & \\
6. & 704 & \\
7. & 220 & \\
8. & 382 & \\
9. & 330 & \\
\end{array}
}
