VULGAR FRACTIONS. A VULGAR FRACTION is a part of a whole number, and is read by first mentioning the upper part of the fraction, and then the lower, thus:, one-sixth; 7, seven-eighths. The upper part of the fraction is called the numerator, and shows the part of a whole number expressed by the fraction; the lower number is called the denominator, and shows the number of such parts contained in a whole number. Vulgar fractions are found under four different situations; namely, proper, improper, compound, and mixed. A proper fraction has its numerator not greater than its denominator; as, 10, 13. 9 An improper fraction has its numerator greater than its denominator; as, 25, 37. A compound fraction is expressed by a fraction of another fraction; as, of of of. A mixed number is a whole number, with a fraction following it; as, 71, 87. A mixed fraction has a fraction attached either to its numerator or denominator. Questions. What is a vulgar fraction; and how is it to be read? What part of a fraction is called the numerator, and what does it show? What part of a fraction is called the denominator, and what does it show? Vulgar fractions are found under four different situations: name them. What is a proper fraction? What is an improper fraction? What is a compound fraction? What is a mixed fraction? REDUCTION OF VULGAR FRACTIONS. To reduce fractions to their lowest terms. Rule. Divide the numerator and denominator continually by any number that will divide them both without a remainder: when they cannot both be divided by the same number without a remainder, that is their lowest term. 2. To reduce a mixed number to an improper fraction. Rule. Multiply the whole number by the denominator of the fraction, to which add the numerator, and place the product over the denominator, for a new numerator. Case 3. To reduce an improper fraction to a whole or mixed number. Rule. Divide the numerator by the denominator, and the product will be a whole number; if there be any remainder, set it over the given denominator, for the numerator of the fraction. Case 4. To reduce a compound fraction to a single fraction. |
