Solve {r}{21/8}{17/8}

$$\left. \begin{array} { r } { 2 \frac { 1 } { 8 } } \\ { 1 \frac { 7 } { 8 } } \end{array} \right.$$

Sort

$$\frac{15}{8},\frac{17}{8}$$

Solution Steps

Multiply 2 and 8 to get 16.

$$sort(\frac{16+1}{8},\frac{1\times 8+7}{8})$$

Add 16 and 1 to get 17.

$$sort(\frac{17}{8},\frac{1\times 8+7}{8})$$

Multiply 1 and 8 to get 8.

$$sort(\frac{17}{8},\frac{8+7}{8})$$

Add 8 and 7 to get 15.

$$sort(\frac{17}{8},\frac{15}{8})$$

To sort the list, start from a single element \frac{17}{8}.

$$\frac{17}{8}$$

Insert \frac{15}{8} to the appropriate location in the new list.

$$\frac{15}{8},\frac{17}{8}$$

Evaluate

$$\frac{17}{8},\ \frac{15}{8}$$
