Question

Moby practiced solving addition and subtracting problems, but he made a mistakes! Explain any error you find, and include what’s the correct answer should be 3/4-5/12=3/12-5/12=-2/12=-1/6

Answer 1

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

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
