Divide JJ by ft DIVISION OF FRACTIONS. 121 To Divide a Fraction by a Fraction, when they have Different Denominators. i. At -J of a dime apiece, how many pears can be pur- chased for j of a dime ? Analysis. — \ dime will buy as many opebation. pears as \ dime is contained times in f 1X4 4 dime.

Cing the fractions to a common denomi- nator, it will be seen that the numerator of each is multiplied into the denominator of the other. This produces the same com- bination of terms and the same results as inverting the divisor and multiplying the terms of the dividend by it. Thus, |-* i i= £ x $=$, or z\ pears, the same as before. Remark. — In dividing, no use is made of the common denomi- nator ; hence, in practice, multiplying the denominators together may be omitted.
