Question

A restaurant had `3` pies, cut into eighths. By noon, `3/4` of all the pieces were sold. How many pieces of pie were sold by noon?

Answer 1

`18` pieces

Explanation:

If each of `3` pies is cut into `8` pieces,
you would have `3xx8=24` pieces of pie

If `3/4` of the pieces were sold,
you would have sold `3/4xx24=3xx6=18` pieces of pie
