Please fill up the required input... We cannot solve it yet--

In this equation, the two denominators are not the same. We need to make the two the same!

The LCD of x and a is LCD. [] and [last] being the factors.

$\frac{x}{y} - \frac{a}{b} = \frac{}{y} - \frac{}{b}$

Now that the denominators are the same, we need to get the numerator of each fraction.

Dividing our current numerator from the old one from the first fraction, then multiplying to the old numerator.

$\frac{x}{y} - \frac{a}{b} = \frac{x}{y} - \frac{}{b}$

Dividing our current numerator from the old one from the second fraction, then multiplying to the old numerator.

$\frac{x}{y} - \frac{a}{b} = \frac{x}{y} - \frac{a}{b}$

After that, simply subtract the fraction together.

$\frac{x}{y} - \frac{a}{b} = \frac{p}{q}$

$\frac{x}{y} = \frac{p}{q}$
