Solve the Fraction Subtraction: 4/5 minus 3/10

Let's begin by identifying the lowest common denominator between 5 and 10.

In order to determine the lowest common denominator, we must find a number that is divisible by both 5 and 10.

In this case, the common denominator is 10.

Now let's proceed to multiply each fraction by the appropriate number to reach the denominator 10.

We'll multiply the first fraction by 2

We'll multiply the second fraction by 1

$\frac{4\times2}{5\times2}-\frac{3\times1}{10\times1}=\frac{8}{10}-\frac{3}{10}$

Finally let's subtract as follows:

$\frac{8-3}{10}=\frac{5}{10}$
