[tex]\huge\text{Hey there!}[/tex]
[tex]\mathsf{\dfrac{14}{20} - \dfrac{81}{90}}[/tex]
[tex]\mathsf{= \dfrac{14\div2}{20\div2} - \dfrac{81\div 9}{90\div9}}[/tex]
[tex]\mathsf{= \dfrac{7}{10} - \dfrac{9}{10}}[/tex]
[tex]\mathsf{= \dfrac{7 - 9}{10 - 0}}[/tex]
[tex]\mathsf{= \dfrac{-2}{10}}[/tex]
[tex]\mathsf{= \dfrac{-2\div 2}{10\div2}}[/tex]
[tex]\mathsf{= \dfrac{-1}{5}}[/tex]
[tex]\huge\text{Therefore, your answer should be:}[/tex]
[tex]\huge\boxed{\mathsf{-\dfrac{1}{5}}}\huge\checkmark[/tex]
[tex]\huge\text{Good luck on your assignment \& enjoy your day!}[/tex]
