Page 24 - A proper fraction is a fraction whose numerator is less than its denominator. Its value is less than 1; as, J, I,-rV80.
Page 182 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
Page 25 - Therefore, multiplying both terms of a fraction by the same number does not alter its value.
Page 97 - In any proportion, the product of the extremes equals the product of the means. Thus, in the proportion, 17 : 51 = 14 : 42.
Page 93 - 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 97 - The first and fourth terms of a proportion are called the extremes; and the second and third terms the means. Thus, in the proportion a : b = с : d, a and d are the extremes, and b and с the means.
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 40 - Place the subtrahend under the minuend, so that the decimal points will be directly under each other. Subtract, as in whole numbers, and place the decimal point in the remainder, directly under the decimal points above.
Page 134 - A circle is a plane figure bounded by a curved line, called the circumference, every point of which is equally distant from a point within called the center.
