Answer: -5/12
Explanation:
Data: 3/12-1/6-1/4-1/4=x
Step one, Find the common demoninator of the fractions
3/12-1/6-1/4-1/4 = 3/12-2/12-3/12-3/12
Reason: You can't subtract fractions that don't have the same denominatory so by finding the common demoninator you allow the problem to be solved.
Step two, Subtract
3/12-2/12= 1/12-3/12=-2/12-3/12=-5/12
Reason: You subtract fractions(With the same denominator) like normal numbers but you keep the denominator the same. When subtracted, the end result is -5/12 since subtracting a bigger number from a smaller number creates a negative.
Answer: -5/12
