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

Hello,

`a\ \textgreater \ 0\ and\ b\ \textgreater \ 0 ==>a+b>0\\ a\ \textgreater \ b ==\ \textgreater \ a+b\ \textgreater \ b+b\\ ==\ \textgreater \ a+b\ \textgreater \ 2b\\ ==\ \textgreater \ 1\ \textgreater \ (2b)/(a+b) \\ ==\ \textgreater \ (1)/(2) \ \textgreater \ (b)/(a+b)`

Answer 2

b/a+b x 0.5 is 11/g+a so The pair is greater
