How can you find an unknown factor in a multiplication problem?

Is the answer: divide the two numbers that you have?

Right.

3 * x = 12
x = 12/3
x = 4

what is the equivalt fraction to 9/12

To find an unknown factor in a multiplication problem, you can use division as one method. Here's the step-by-step process:

1. Identify the numbers involved in the multiplication problem.
2. Determine which number is the product (the result of the multiplication) and which number is the known factor.
3. Write down the known factor and the product.
4. Divide the product by the known factor.
5. The result of the division will give you the value of the unknown factor.

For example, let's say you have the problem 4 × X = 24, and you need to find the value of X (the unknown factor):

1. The numbers involved are 4 (known factor) and 24 (product).
2. The product is 24, and the known factor is 4.
3. Write down the equation as 4 × X = 24.
4. Divide 24 by 4: 24 ÷ 4 = 6.
5. The value of X is 6, so the unknown factor in the original problem is 6.

Therefore, in this case, the answer is correct. You found the unknown factor by dividing the two numbers you had.
