Question

What’s 14/20 - 81/90

Answer 1

$\huge\text{Hey there!}$

$\mathsf{\dfrac{14}{20} - \dfrac{81}{90}}$

$\mathsf{= \dfrac{14\div2}{20\div2} - \dfrac{81\div 9}{90\div9}}$

$\mathsf{= \dfrac{7}{10} - \dfrac{9}{10}}$

$\mathsf{= \dfrac{7 - 9}{10 - 0}}$

$\mathsf{= \dfrac{-2}{10}}$

$\mathsf{= \dfrac{-2\div 2}{10\div2}}$

$\mathsf{= \dfrac{-1}{5}}$

$\huge\text{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{-\dfrac{1}{5}}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
