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
`(b)/(a+b)=(b)/(b+b)=0.5`

Since a > b, then a + b > b + b and thus
`(b)/(a+b)<(b)/(b+b)`

Therefore,
`(b)/(a+b)<0.5`
