Compare 5 13 and - 11 13 .

We are given to compare 5 13 and - 11 13 . First, we shall find the absolute values of 5 13 and - 11 13 and compare them. The absolute value of a rational number is the distance of the rational number from 0 on the number line. It is always positive. We can write, - a = + a = + a , where a is any number. Thus, we get, 5 13 = 5 13 and - 11 13 = 11 13 . We know, when comparing the rational numbers with the same denominator, we have to compare their numerators. The rational number with the smaller numerator is smaller. Comparing the numerators of 5 13 and 11 13 , we obtain, 5 < 11 . Hence, 5 13 < 11 13 and therefore, 5 13 < - 11 13 .
