Or the third term of the proportion may be multiplied by the denominator of the fraction representing the aliquot part.

The denominator of decimals is never written, the dot placed before the first figure of the numerator expressing its value.

A vulgar fraction is reduced to a decimal by dividing the numerator (increased sufficiently with ciphers) by the denominator.

One factor in the numerator and one in the denominator make a “pair” of factors.

Look up the method of solving when the unknowns are in the denominator.

It is then indicated at the extreme right of the denominator (fig. 353).

What is the difference between the numerator and the denominator?

Any two fractions will do if the denominator equals the sum of the two numerators.

What have we done with the numerator and denominator in every case?

The terms numerator and denominator are connected with the upper and lower numbers composing a fraction.
