Q. Evaluate the expression shown below and write your answer as a fraction in simplest form.\newline1213713 -\frac{12}{13}-\frac{7}{13} \newlineAnswer:
  1. Identify like fractions: Identify like fractions.\newlineBoth fractions have the same denominator, which is 1313, so they are like fractions and can be combined by adding or subtracting their numerators.
  2. Subtract numerators: Subtract the numerators.\newlineSubtract the numerators of the two fractions while keeping the common denominator the same.\newline1213713=12713-\frac{12}{13} - \frac{7}{13} = \frac{-12 - 7}{13}
  3. Perform subtraction: Perform the subtraction.\newlineCalculate the sum of the numerators.\newline127=19-12 - 7 = -19
  4. Write result as fraction: Write the result as a fraction. Place the result of the subtraction over the common denominator. (19)/13(-19) / 13
  5. Simplify fraction: Simplify the fraction if possible.\newlineCheck if the fraction can be simplified. In this case, 19-19 and 1313 have no common factors other than 11, so the fraction is already in its simplest form.
