Answer
$\frac{53}{5}$
Work Step by Step
To write $10\frac{3}{5}$ as a mixed number, we must multiply the whole number in front of the fraction and the denominator together.
$10\times5=50$
Next, take the sum of the number above and the numerator.
$50+3=53$
This will be the numerator of the mixed number. We will use the original denominator as the denominator of the mixed number. Therefore, $10\frac{3}{5}=\frac{53}{5}$.
