Solve 121/9+(-33/9)

$$12 \frac { 1 } { 9 } + ( - 3 \frac { 3 } { 9 } )$$

Evaluate

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

Solution Steps

Multiply 12 and 9 to get 108.

$$\frac{108+1}{9}-\frac{3\times 9+3}{9}$$

Add 108 and 1 to get 109.

$$\frac{109}{9}-\frac{3\times 9+3}{9}$$

Multiply 3 and 9 to get 27.

$$\frac{109}{9}-\frac{27+3}{9}$$

Add 27 and 3 to get 30.

$$\frac{109}{9}-\frac{30}{9}$$

Since \frac{109}{9} and \frac{30}{9} have the same denominator, subtract them by subtracting their numerators.

$$\frac{109-30}{9}$$

Subtract 30 from 109 to get 79.

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

Factor

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