Step-by-step explanation:

so, is it really 3/12, or is it as you typed it : 3 - 12 ?

in the first case we have to simplify the fraction. that means we divide the top (numerator) and the bottom (denominator) by the same number to get still integers for the numerator and denominator.

in this case we can devide both 3 and 12 by 3 and get a simplified fraction

1/4

in the second case we do the subtraction :

3 - 12 = -9

remember, doing a subtraction "into the negative numbers" is like doing the inverted subtraction into the positive numbers and then invert the sign :

12 - 3 = 9

so,

3 - 12 = -9
