Divide both the numerator and denominator by any number that will
leave no remainder and repeat the operation until no number will
divide them both.
_Example_. The simplest form of 36/45 is found by dividing by 9 = 4/5.
To reduce a whole number and a fraction, as 4-1/2, to fractional form,
multiply the whole number by the denominator, add the numerator and
write the result over the denominator. Thus, 4 X 2 = 8 + = 9 placed
over 2 is 9/2.
