Answer:
or 0.5 in decimal form
Explanation:
The expression is
Find Least Common Multiplier (LCM) of the denominators
This is
the product of the two denominators
Multiply entire equation by this LCM:
We get
Simplify the first term
Simplify the second term
RHS is
Therefore we get
Expand the first term using the FOIL method
Here a = 1, b = 2. So
Expanding
gives us
(Use the FOIL method:
Here a = -2, b = -3. Note there is a negative sign before the entire expression)
So the original expression is
Collecting like terms
=
Add 4 to both sides
Divide both sides by 8:
or
in decimal
