Solve the Fraction Subtraction: 4/5 - 5/10 Step by Step

Solve the following equation:

$\frac{4}{5}-\frac{5}{10}=$

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

In order to identify 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

Let's proceed to multiply each fraction by the appropriate number in order to reach the denominator 10.

We'll multiply the first fraction by 2

We'll multiply the second fraction by 1

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

Finally let's subtract as follows:

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