$a + \frac{1}{4} = \frac{3}{4}$

Step 1

Subtract $\frac{1}{4}$ from both sides of the equation.

$a = \frac{3}{4} - \frac{1}{4}$

Step 2

Combine the numerators over the common denominator.

$a = \frac{3 - 1}{4}$

Step 3

Subtract $1$ from $3$ .

$a = \frac{2}{4}$

Step 4

Cancel the common factor of $2$ and $4$ .
