To Reduce a Decimal Fraction to a Vulgar Fraction.
Write the decimal as the numerator of the fraction and set
under it for the denominator the figure one, followed by as
many ciphers as there are decimal places ; then cancel the frac-
tion thus written, to its smallest possible terms.
Example.
Reduce 0.3125 to a vulgar fraction.
Solution
:
0.3125 = TVo¥o> cancelling this by five we have a
6
o¥o — iff
= to — rV
To Reduce a Decimal Fraction to a Given Vulgar Fraction
of Approximately the Same Value.
Multiply the decimal by the number which is denomi-
nator in the fraction to which the decimal shall be reduced,
and the product is the numerator in the fraction.
Example.
Reduce 0.484375 to sixteenths, thirty-seconds and sixty-
fourths.
