Σελίδα 59 - FRACTIONS, MULTIPLY THE NUMERATORS TOGETHER, FOR A NEW NUMERATOR, AND THE DENOMINATORS TOGETHER, FOR A NEW DENOMINATOR.
Σελίδα 31 - MULTIPLYING BY A WHOLE NUMBER is TAKING THE MULTIPLICAND AS MANY TIMES, AS THERE ARE UNITS IN THE MULTIPLIER.
Σελίδα 188 - But it is commonly necessary that this first proportion should pass through a number of transformations before it brings out distinctly the unknown quantity, or the proposition which we wish to demonstrate. It may undergo any change which will not affect the equality of the ratios ; or which will leave the product of the means equal to the product of the extremes.
Σελίδα 231 - Divide the first term of the dividend by the first term of the divisor, and write the result as the first term of the quotient. Multiply the whole divisor by the first term of the quotient, and subtract the product from the dividend.
Σελίδα 290 - Thus the proposition, that the sum of the three angles of a triangle is equal to two right angles, (Euc.
Σελίδα 134 - Two travellers A and B set out to meet each other, A leaving the town C, at the same time that B left D.
Σελίδα 216 - If the first term of an increasing arithmetical series is 3, the common difference 2, and the number of terms 20 ; what is the sum of the series 1 Ans.
Σελίδα 185 - When there ka series of quantities, such that the ratios of the first to the second, of the second to the third, of the third to the fourth, &c. are all equal ; the quantities are said to be in continued proportion.
Σελίδα 42 - As the product of the divisor and quotient is equal to the dividend, the quotient may be found, by resolving the 'dividend into two such factors, that one of them shall be the divisor. The other will, of course, be the quotient. Suppose abd is to be divided by a. The factor a and bd .will produce the dividend. The first of these, being a divisor, maybe set aside.
Σελίδα 224 - There are three numbers in geometrical progression, the greatest of which exceeds the least by 15; and the difference of the squares of the greatest and the least,. is to the sum of the squares of all the three numbers as 5 to 7. What are the numbers 1 Ans.
