How many spaces of time, each 5 minutes, in 120 minutes ? Ans. 24. 52. If a stick of timber 89 feet long, be divided into 7 equal parts, what will be the length of each part 2 Ans. 12# feet. 53. If a stick of timber 100 feet long, be divided into divisions of 8 feet each, how many divisions will it consist of 2 - Ans. 124. Contraction 2. When any of the places at the right of the divisor, are occupied by ciphers, they may be omitted, and an equal number of figures must be omitted at the right of the dividend. The figures cut off from the dividend, must be brought to the right of the remainder, if any, if not, they will constitute the whole remainder. 54. What is the quotient of 8'990°123, divided by 762300 ° Illustration of contraction 2. —We obtain the same quotient, whether we omit the ciphers and an equal number of figures at the right hand of the dividend, or retain them, because the ciphers on the right of the divisor, will always come under an equal number of figures brought from the right of the dividend; and as they do not lessen the figures above them by subtracting, the figures above them the last time we subtract, which were brought from the right hand of the dividend, will always be left as a remainder, or a part of it. By examining the two last operations, it will be seen that we obtain the same quotient and the same remainder, by both methods. The scholar is required to perform the following examples, as directed by the sign of division : When the divisor is 1 with a cipher, or ciphers, to the right hand, we have only to cut off as many figures at the right hand of the dividend, as there are ciphers in the divisor;-the figures cut off will be the remainder, and the others, the quotient. 61. Divide 123456789 by 10'000. Operation by the common method. Illustration of contraction 3.--The figure 1 in the divisor, can be taken from every figure in the dividend as many times as there are 1's in the figures of the dividend; consequently, the figures in the quotient must be the same as the left hand figures of the dividend. As the ciphers in the divisor will come under an equal number of figures at the right hand of the dividend, those figures will always remain. See the operation and contraction of the last example. 62. What is the quotient of ninety thousand and nine, divided by one thousand. Ans. 90 roorg. 63. Divide one million and one, by one million.
