If they are of different denominations, 'or in high terms, reduce them as directed in Addition of Vulgar Fractions. 2. Subtract the lesser numerator from the greater, and under the remainder place the common denominator. Note 1. When whole numbers are given with fractions, the lower numerator will sometimes be the greatest, in which case subtract it from the denominator, and to the remainder add the upper numerator, and carry one to the unit's place of the lower whole number. Nare 2. This rule is proved by addition. EXAMPLES. 1. From 113 take . 111 3 112 4 Ans. 379 TOO 7 21 8131 Ans. 3. From 141 take of 19. Ans.l's 4. From 100 take 5. From 96 take . Ans. 95. 6. From of 76, take of 21. Ans. 7. From 11%, take jol, of 2640=70 8. From 715 take is. Ans. 7035. Note.

Prepare the given fraction by reduction (if necessary) by reducing them to their lowest terms, if mixed fractions, reduce to single ones. 2. Multiply the numerators together for a new numerator. 3. Multiply the denominators together for a new deminator. NOTE. When any number, either whole, fractional, or mised, is multiplied by a fraction, the product will be less than the multiplicand, in the same proportion as the multiplying fraction is less than 1, or an unit. In Division of Vulgar Fractions prepare the given fractions (if necessary) as for multiplication ; then invert |
