We can write the ratios 1 : 4 and 3 : 10 as fractions :
[tex]\text{$\displaystyle\frac{1}{4} $}[/tex]
and
[tex]\text{$\displaystyle\frac{3}{10} $}[/tex]
Put the fractions together :
[tex]\text{$\displaystyle\frac{1}{4} \:and\:\frac{3}{10}$}[/tex]
Both fractions are in their simplest form ; the numerator and denominator do not have any common factors , except 1 , and there's no point in dividing by 1.
