RULE.

Multiply each numerator into all the denominators except its own, for the new numerators, and all the denominators together for a common denominator.

RULE.

Reduce the fractions, if necessary, to a common denominator : then add the numerators together and place their sum over the common denominator.

cxbxf=cbf the new numerators.
exbxd=ebd

And.. bxdxf=bdf the common denominator.

I. Reduce the fractions to a common denominator.

II. Subtract the numerator of the fraction to be subtracted from the numerator of the other fraction, and place the difference over the common denominator.

If the quantities to be multiplied are mixed, reduce them to a fractional form; then multiply the numerators together for a numerator and the denominators together for a denominator.

5. It is required to find the product of b+- and

a

Ꮖ

ab+bx

Reduce the mixed quantities, if there are any, to a fractional form : then invert the terms of the divisor and multiply the fractions together as in the last case.
