Answer:
- [tex]\frac{5}{12}[/tex]
Step-by-step explanation:
Before adding/ subtracting the fractions we require them to have a common denominator.
Two of the fractions have a denominator of 12 and we can change the middle fraction to this denominator by multiplying numerator/denominator by 3
[tex]\frac{1}{4}[/tex] = [tex]\frac{1(3)}{4(3)}[/tex] = [tex]\frac{3}{12}[/tex]
Note that +(- ) = -
We can now express as
- [tex]\frac{5}{12}[/tex] - [tex]\frac{3}{12}[/tex] + [tex]\frac{3}{12}[/tex]
= - [tex]\frac{5}{12}[/tex] + 0 = - [tex]\frac{5}{12}[/tex]
