A ream of paper contains 500 sheets of paper. Norm has 373 sheets of paper left from a ream. Express the portion of a ream Norm has as a fraction and as a decimal.

The fraction is the ratio of the paper left to the number of papers in the ream originally:
${\displaystyle \frac{373}{500}}$
Note that this is the simplest form.
Using the fraction, multiply both the numerator and denominator by 2 so that the denominator becomes 1000. This makes finding the decimal easier as you only need to move the decimal point 3 places to the left:
${\displaystyle \frac{373}{500}\times \frac{2}{2}=\frac{746}{1000}}$
${\displaystyle \frac{373}{500},0,746}$
