ARITHMETIC. 17<br />

(36) The value of a fraction is obtained by dividing the<br />

the denominator.<br />

numerator by<br />

13<br />

To obtain the value of the fraction — we divide the num-<br />

Z<br />

erator 13 by<br />

the denominator 2. 2 is contained in 13 six<br />

times, with 1 remaining. This 1 remaining<br />

is written over<br />

the denominator 2, thereby making the fraction — , which is<br />

annexed to the whole number G, and we obtain 6— as the<br />

z<br />

mixed number. The reason for performing this operation is<br />

the following :<br />

2 13<br />

In 1 there are — (two halves), and in — (thir-<br />

Z 2<br />

teen halves) there are as many units (1)<br />

as 2 is contained<br />

times in 13, which is<br />

6, and —<br />

(one-half) unit remaining.<br />

z<br />

13 11<br />

Hence, — = 6 + — = 6-, the required mixed number. Ans.<br />

other words, turn it upside down) and proceed as in multi-<br />
