a) \( 387: 9=43 \) -36 -27 -27

To solve the problem \( 387: 9 = 43 \), we need to check if the division is correct. Let's perform the division: \( 387 \div 9 \) To do this, we can use long division: ``` 43 ---- 9 | 387 - 36 ---- 27 -27 ---- 0 ``` Here's the step-by-step process: 1. 9 goes into 38 once, so we write down 4 above the line. 2. Multiply 4 by 9 to get 36, and subtract 36 from 38 to get 2. 3. Bring down the next digit, which is 7, to make 27. 4. 9 goes into 27 three times, so we write down 3 above the line. 5. Multiply 3 by 9 to get 27, and subtract 27 from 27 to get 0. Since the remainder is 0, the division is exact, and the quotient is 43. Therefore, the correct answer is: \( 387 \div 9 = 43 \) The options you provided (-36, -27, -27) are not correct for this division problem. The correct answer is 43.
