Common fractions may often be changed to decimals very readily, and the calculations thereby made much easier.
TO CHANGE COMMON FRACTIONS TO DECIMALS.
Annex one or more ciphers to the numerator and divide by the denominator.
Example. Change 3/4 to a decimal. Ans..75.
We add two ciphers to the 3, making it 300, and divide by 4, which gives us.75. In the same way 1/2 =.5, or 3/4 =.75, and so on. When a quantity is in dollars and fractions of a dollar, the fractions should always be thus reduced to cents and mills.
