Solve 12/3m-1/6m

$$1 \frac { 2 } { 3 m } - \frac { 1 } { 6 m }$$

Evaluate

$$\frac{1}{2m}$$

Short Solution Steps

Express 1\times \frac{2}{3m} as a single fraction.

$$\frac{2}{3m}-\frac{1}{6m}$$

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3m and 6m is 6m. Multiply \frac{2}{3m} times \frac{2}{2}.

$$\frac{2\times 2}{6m}-\frac{1}{6m}$$

Since \frac{2\times 2}{6m} and \frac{1}{6m} have the same denominator, subtract them by subtracting their numerators.

$$\frac{2\times 2-1}{6m}$$

Do the multiplications in 2\times 2-1.

$$\frac{4-1}{6m}$$

Do the calculations in 4-1.

$$\frac{3}{6m}$$

Differentiate w.r.t. m

$$-\frac{1}{2m^{2}}$$
