When the denominatus no two or more fractions are the same, the fractions are said to have a common denominator. Thus and if have a common denominator. We have seen that, when two or more fractions have a common denominator, they may be added and subtracted as weil as whole numbers. We add or subtract the numerators, and write their sum or difference over the common denominator. The first part of the process in the above examples was to reduce them to a common denoininator.

76. Reduce and to a common denomina or. Nore. They may be reduced to twelfths.

If it cannot be immediately seen what number must be the common denominator, it may be found, by multiplying all the denominators together ; for that will always produce a number divisible by all the denominators.

77. Reduce f and if to a common denominator.

78. Reduce s and and if to a common denom inator.

79. Reduce f and to a common denominator. 30. Reduce 4 and to a common denominator
