To multiply two numbers with two digits, it is easiest to use the traditional algorithm of multiplication. When multiplying 650 and 70, we first multiply 0 (the ones digit of 70) by 650, which equals 0. We then multiply 7 (the tens digit of 70) by 650, which equals 4550. Finally, we add these two products: 0 + 4550 = 4550. Therefore, the answer is 45,500, which corresponds to choice D. To multiply, we start with the ones column: 0 multiplied by 650 is 0. Moving to the tens column, 7 multiplied by 0 is 0, so we write a 0 in the tens column and carry over the 4 to the next column. Next, we have 7 multiplied by 5, which is 35, plus the carried-over 4, for a total of 39. We write the 9 in the hundreds column and carry over the remaining 3. Finally, we have 7 multiplied by 6, which is 42, plus the carried-over 3, for a total of 45. Therefore, our final answer is 45,500. The correct answer is D.
