Welcome to the Fraction Formulator! Today you're going to build various
fractions.

You can either use the arrows or type in a number for the numerator
and denominator.

Your fraction will then be displayed in the form of a pizza and
a divided rectangle.

You can play for as little or as long as you want. There are no time
restrictions.

You can now experiment with equivalent fractions as well!

Try adjusting the multiplier and see what happens.

Note: on small mobile devices, you may have to scroll or rotate your
device to see everything.

You're not allowed to make improper fractions (where the top number, or numerator
is larger than the bottom number, or denominator).
