Página 452 - To reduce a mixed number to an improper fraction, multiply the integer by the denominator of the fraction, add the numerator to the product, and place the result over the denominator.

Página 452 - When the denominators are not alike, we know that the units are divided into unequal parts, so before adding them we must find a common denominator for the denominators of all the fractions. Reduce the fractions to fractions having this common denominator, add the numerators, and write the sum over the common denominator. In this case, the least common denominator, or the least number that will contain all the denominators, is 16; hence, we must reduce all these fractions to loths and then add their...

Página 439 - J n cm me An examination of each of these examples, will show that the process consists in reducing the quantities to a common denominator, and then dividing the numerator of the dividend, by the numerator of the divisor. But, as the common denominator of the fraction is not used in performing the division, the result will be the same as if we invert the divisor, and proceed as in multiplication. Hence, the RULE, FOR DIVIDING AN INTEGRAL OR FRACTIONAL QUANTITY BY A FRACTION.
