Basic Math Examples

$n - \frac{1}{2} = - \frac{1}{4}$

Step 1

Add $\frac{1}{2}$ to both sides of the equation.

$n = - \frac{1}{4} + \frac{1}{2}$

Step 2

To write $\frac{1}{2}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$n = - \frac{1}{4} + \frac{1}{2} \cdot \frac{2}{2}$

Step 3

Write each expression with a common denominator of $4$ , by multiplying each by an appropriate factor of $1$ .

Step 3.2

Multiply $2$ by $2$ .

$n = - \frac{1}{4} + \frac{2}{4}$

Step 4

Combine the numerators over the common denominator.

$n = \frac{- 1 + 2}{4}$

Step 5

Add $- 1$ and $2$ .

$n = \frac{1}{4}$
