Solve 4/m-n/3

$$\frac { 4 } { m } - \frac { n } { 3 }$$

Evaluate

$$-\frac{n}{3}+\frac{4}{m}$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of m and 3 is 3m. Multiply \frac{4}{m} times \frac{3}{3}. Multiply \frac{n}{3} times \frac{m}{m}.

$$\frac{4\times 3}{3m}-\frac{nm}{3m}$$

Since \frac{4\times 3}{3m} and \frac{nm}{3m} have the same denominator, subtract them by subtracting their numerators.

$$\frac{4\times 3-nm}{3m}$$

Do the multiplications in 4\times 3-nm.

$$\frac{12-nm}{3m}$$

Factor

$$\frac{12-mn}{3m}$$
