Solve 131/9-43/9=

$$13 \frac { 1 } { 9 } - 4 \frac { 3 } { 9 } =$$

Evaluate

$$\frac{79}{9}\approx 8.777777778$$

Solution Steps

Multiply 13 and 9 to get 117.

$$\frac{117+1}{9}-\frac{4\times 9+3}{9}$$

Add 117 and 1 to get 118.

$$\frac{118}{9}-\frac{4\times 9+3}{9}$$

Multiply 4 and 9 to get 36.

$$\frac{118}{9}-\frac{36+3}{9}$$

Add 36 and 3 to get 39.

$$\frac{118}{9}-\frac{39}{9}$$

Since \frac{118}{9} and \frac{39}{9} have the same denominator, subtract them by subtracting their numerators.

$$\frac{118-39}{9}$$

Subtract 39 from 118 to get 79.

$$\frac{79}{9}$$

Factor

$$\frac{79}{3 ^ {2}} = 8\frac{7}{9} = 8.777777777777779$$
