A CASE IV. 55. To reduce fractions having different denominators to equivalent fractions having a common denominator. RULE. Multiply each numerator into all the denominators except its own, for the new numerators, and all the denominators together for a common denominator. EXAMPLES. 1. Reduce , 3, and #, to a common denominator. NotE.-It is plain that this reduction does not alter the values of the several fractions, since the numerator and denominator of each are multiplied by the same number. b 2. Reduce + and + to equivalent fractions having a common denominator. a × 0–6, $ × b=&” and bx e-be, the common denominator. ; the new numerators. QUEst.—55. How do you reduce fractions to a common denominator? CASE W.56. To add fractional quantities together. RULE. Reduce the fractions, if necessary, to a common denominator; then add the numerators together, and place their sum over the common denominator. 35+30+30+ 30 which, by reducing to the lowest term me 4}}. - 0. c e 2.
