Solve {r}{91/5}{-22/5}

$$\left. \begin{array} { r } { 9 \frac { 1 } { 5 } } \\ { - 2 \frac { 2 } { 5 } } \end{array} \right.$$

Evaluate

$$\frac{34}{5}=6.8$$

Solution Steps

Multiply 9 and 5 to get 45.

$$\frac{45+1}{5}-\frac{2\times 5+2}{5}$$

Add 45 and 1 to get 46.

$$\frac{46}{5}-\frac{2\times 5+2}{5}$$

Multiply 2 and 5 to get 10.

$$\frac{46}{5}-\frac{10+2}{5}$$

Add 10 and 2 to get 12.

$$\frac{46}{5}-\frac{12}{5}$$

Since \frac{46}{5} and \frac{12}{5} have the same denominator, subtract them by subtracting their numerators.

$$\frac{46-12}{5}$$

Subtract 12 from 46 to get 34.

$$\frac{34}{5}$$

Factor

$$\frac{2 \cdot 17}{5} = 6\frac{4}{5} = 6.8$$
