The first step for solving this expression is to subtract the whole numbers and the fractional parts of the mixed numbers separately. This process will look like the following: (5 - 4) + ([tex] \frac{1}{8} [/tex] - [tex] \frac{1}{8} [/tex]) Now subtract the numbers in the first parenthesis. 1 + ([tex] \frac{1}{8} [/tex] - [tex] \frac{1}{8} [/tex]) Then subtract the fractions in the second parenthesis. 1 + 0 Since we are adding 1 to 0,, the quantity will not change so our final answer is going to be 1.
