Question

Show a model showing 1/4 = ___/12. Fill in the blank with the correct number.

Answer 1

To find a common denominator between 4 and 12, we can see that the number 12 is divisible by 4. Therefore, we can multiply the numerator and denominator of 1/4 by 3 to get:

1/4 = (1 * 3) / (4 * 3) = 3/12

So, the blank should be filled with the number 3.
