1 answer

To find the missing factor, we can set up the equation based on the problem statement:

33,000 ÷ x = 110.

To find x, we can multiply both sides of the equation by x and then by 110:

x = 33,000 ÷ 110.

Now, let's simplify 33,000 ÷ 110:

  1. We can break it down:
    • 33,000 ÷ 11 = 3,000 (since 33 ÷ 11 = 3).
    • Now, we can multiply 3,000 by 10 (because we divided by 11 instead of 110).

So, 33,000 ÷ 110 = 3,000.

Now we can validate that:

3,000 multiplied by 110 equals 33,000, confirming our calculation is correct.

Among the options given, the correct answer is:

3,000.
