Quizplus · Accepted Answer

To subtract the given mixed numbers, you subtract the whole numbers and the fractions separately. $14 - 4 = 10$ and $\frac{5}{8} - \frac{7}{8} = -\frac{2}{8} = -\frac{1}{4}$. Since you can't have a negative fraction when subtracting like this, you take 1 from the whole number part (making it 9) and then add the fraction to a whole (1 - $\frac{1}{4}$ = $\frac{3}{4}$). Thus, the answer is $9 \frac{3}{4}$.
