ORAL EXERCISES. GENERAL NOTE ON MULTIPLICATION OF FRACTIONS.—Multiply { by The multiplier is of 1, or ở of 5. Multiplying å by the whole of 5, we get leo. But we were not to multiply by 5, but by of 5. Having multiplied by a multiplier 6 times the true multiplier, the product is six times as large as it ought to be. Hence we divide by 6 to obtain the true product, which is done by multiplying the denominator of the multiplicand by 6. Thus• ART. 153.-1. At of a dollar apiece, how much will 3 books cost ? Solution.—Three books will cost 3 times of a dollar, or ; of a dollar, equal to 14 dollars. The result is obtained by multiplying the numerator of the fraction by the whole number and writing the product over the denominator. 2.
