Solve 19-70/9+80/9

$$19 - \frac { 70 } { 9 } + \frac { 80 } { 9 }$$

Evaluate

$$\frac{181}{9}\approx 20.111111111$$

Solution Steps

Convert 19 to fraction \frac{171}{9}.

$$\frac{171}{9}-\frac{70}{9}+\frac{80}{9}$$

Since \frac{171}{9} and \frac{70}{9} have the same denominator, subtract them by subtracting their numerators.

$$\frac{171-70}{9}+\frac{80}{9}$$

Subtract 70 from 171 to get 101.

$$\frac{101}{9}+\frac{80}{9}$$

Since \frac{101}{9} and \frac{80}{9} have the same denominator, add them by adding their numerators.

$$\frac{101+80}{9}$$

Add 101 and 80 to get 181.

$$\frac{181}{9}$$

Factor

$$\frac{181}{3 ^ {2}} = 20\frac{1}{9} = 20.11111111111111$$
