Page 53 - The terms of a ratio are the two numbers to be compared; thus, in the above ratio, 20 and 4 are the terms. When both terms are considered together, they are called a couplet ; when considered separately, the first term is called the antecedent, and the second term the consequent. Thus, in the ratio 20 : 4, 20 and 4 form a couplet, and 20 is the antecedent, and 4 the consequent.

Page 12 - Operations with Fractions A) To change a mixed number to an improper fraction, simply multiply the whole number by the denominator of the fraction and add the numerator.
Page 24 - Multiplying or dividing both terms of a fraction by the same number does not change the value of the fraction.
Page 11 - The number thus added to itself, or the number to be multiplied, is called the multiplicand. The number which shows how many times the multiplicand is to be taken, or the number by which we multiply., is called the multiplier.
Page 24 - Therefore, multiplying both terms of a fraction by the same number does not alter its value.
Page 42 - Point off as many decimal places in the quotient as there are ciphers annexed.
Page 16 - The number to be divided, is called the dividend. The number by which we divide, is called the divisor.
