Question

Suppose a and b give the population of two states where a>b . Compare the expressions and tell which of the given pair is greater or if the expression are equal.

b/a+b and 0.5

Answer 1

Suppose a = b, then $\frac{b}{a+b}=\frac{b}{b+b}=0.5$

Since a > b, then a + b > b + b and thus $\frac{b}{a+b}<\frac{b}{b+b}$

Therefore, $\frac{b}{a+b}<0.5$
