To solve 865 × 9, we use long multiplication. Step 1: Multiply the units digit of 865 (which is 5) by 9. 5 × 9 = 45 Write down 5 and carry over 4. Step 2: Multiply the tens digit of 865 (which is 6) by 9, and add the carried over 4. 6 × 9 = 54; 54 + 4 = 58 Write down 8 and carry over 5. Step 3: Multiply the hundreds digit of 865 (which is 8) by 9, and add the carried over 5. 8 × 9 = 72; 72 + 5 = 77 Write down 77. The full calculation is: c × 865 × 00 9 × 7785 The final answer is 7785.

7785

Step-by-step solution

3 steps

To solve $865 \times 9$ , we use long multiplication.

Multiply the units digit of 865 (which is 5) by 9.
$5 \times 9 = 45$
Write down 5 and carry over 4.
Multiply the tens digit of 865 (which is 6) by 9, and add the carried over 4.
$6 \times 9 = 54$ $54 + 4 = 58$
Write down 8 and carry over 5.
Multiply the hundreds digit of 865 (which is 8) by 9, and add the carried over 5.
$8 \times 9 = 72$ $72 + 5 = 77$
Write down 77.

The full calculation is:
$\begin{array}{c} \phantom{\times} 865 \\ \underline{\times \phantom{00} 9} \\ \phantom{\times} 7785 \\ \end{array}$
The final answer is 7785.
