Σελίδα xix - Multiply each payment by its term of credit, and divide the sum of the products by the sum of the payments ; the quotient will be the average term of credit.
Σελίδα viii - Reduce the fractions to a common denominator and divide the numerator of the dividend by the numerator of the divisor.
Σελίδα ii - I. Write the divisor at the left of the dividend, with a line between them.
Σελίδα vi - Multiplying or dividing both terms of a fraction by the same number does not alter the value of the fraction.
Σελίδα 126 - Multiply the sum of the parallel sides by the perpendicular distance between them, and half the product will be the area.
Σελίδα vii - To reduce a mixed number to an improper fraction, — RULE : Multiply the whole number by the denominator of the fraction, to the product add the numerator, and write the result over the denominator.
Σελίδα iii - RULE. Divide the given number by any prime factor ; divide the quotient in the same manner, and so continue the division until the quotient is a prime number.
