L.C.M. of the denominators is 10.
So, keep the denominators and subtract the numerators.
[tex]\frac{5}{10} -\frac{3}{10} =\frac{5-3}{10}[/tex]
[tex]=\frac{2}{10}[/tex]
Now, simplify the fraction.
To simplify, divide the numerator and the denominator by the common factor 2.
[tex]\frac{5}{10} -\frac{3}{10} =\frac{2}{10}[/tex]
[tex]=\frac{1}{5}[/tex]
Hence, [tex]\frac{5}{10} -\frac{3}{10} =\frac{1}{5}[/tex].
