Solve the Fraction Subtraction: 3/6 - 1/4

Let's try to find the lowest common denominator between 4 and 6

To find the lowest common denominator, we need to find a number that is divisible by both 4 and 6

In this case, the common denominator is 12

Now we'll multiply each fraction by the appropriate number to reach the denominator 12

We'll multiply the first fraction by 2

We'll multiply the second fraction by 3

$\frac{3\times2}{6\times2}-\frac{1\times3}{4\times3}=\frac{6}{12}-\frac{3}{12}$

Now let's subtract:

$\frac{6-3}{12}=\frac{3}{12}$
