Fitzgerald · Answer 1

3/4 - 5/12 = 4/12 - 5/12 = - 1/12

Step-by-step explanation:

Moby's addition and subtracting problem is as follows: Let us break the problem into solvable parts.

3/4 - 5/12

we will find the common factor of the denominator which are 4 and 12. The common factor is 12. We divide 12 by both denominator and multiply by the numerator.

3/4-5/12 = (9 - 5) / 12 = 4/12. This is his first error. 3/4 - 5/12 is equal to 4/12 not 3/12.

Now let us go to the second part which is the answer minus 5/12

4/12 - 5/12 = (4 - 5) / 12 = - 1/12

The final answer should be - 1/12. This is another error that has been detected.

The correct answer combination should be as follows.

3/4 - 5/12 = 4/12 - 5/12 = - 1/12
