Solve -1/em*1/4-1

$$- \frac { 1 } { e m } \times \frac { 1 } { 4 } - 1$$

Evaluate

$$\frac{-4em-1}{4em}$$

Short Solution Steps

Multiply -\frac{1}{em} times \frac{1}{4} by multiplying numerator times numerator and denominator times denominator.

$$\frac{-1}{em\times 4}-1$$

To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{em\times 4}{em\times 4}.

$$\frac{-1}{em\times 4}-\frac{em\times 4}{em\times 4}$$

Since \frac{-1}{em\times 4} and \frac{em\times 4}{em\times 4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-1-em\times 4}{em\times 4}$$

Do the multiplications in -1-em\times 4.

$$\frac{-1-4em}{em\times 4}$$

Factor

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