Question

The fraction 810\dfrac{8}{10} and 15\dfrac{1}{5} have been shaded on this fraction wall.


What is 810−15\dfrac{8}{10} - \dfrac{1}{5}?

The fraction wall can be used to graphically see the difference as 610\dfrac{6}{10}.

Alternatively,
810−15\dfrac{8}{10} - \dfrac{1}{5} = 810−210\dfrac{8}{10} - \dfrac{2}{10}
= 610\dfrac{6}{10}
