QuestionFind the sum of $12 \frac{3}{8}, 17 \frac{4}{5} \& 21 \frac{1}{4}$

Studdy Solution
Convert $\frac{2057}{40}$ back to a mixed number.
Divide $2057$ by $40$:
$2057 \div 40 = 51 \quad \text{remainder} \quad 17$
Thus, $\frac{2057}{40} = 51 \frac{17}{40}$.
The sum of $12 \frac{3}{8}$, $17 \frac{4}{5}$, and $21 \frac{1}{4}$ is:
$\boxed{51 \frac{17}{40}}$
