The expression you provided is:

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

To subtract $\frac{1}{4}$ from 2, we can rewrite 2 as a fraction with a denominator of 4, which would be $\frac{8}{4}$. Now the expression becomes:

$\frac{8}{4} - \frac{1}{4}$

Perform the subtraction:

$\frac{8 - 1}{4} = \frac{7}{4}$

So, $2 - \frac{1}{4} = \frac{7}{4}$, which can also be written as 1.75 in decimal form.
