Answer:
We are given that a>b.
1) [tex]\dfrac{b}{a+b}[/tex] and 0.5
we know that a>b
⇒ a+b>b+b
⇒a+b>2b
⇒ [tex]\dfrac{b}{a+b}<\dfrac{1}{2}=0.5[/tex]
2) a+13c and b+13c is the population of a third state.
so, a+13c>b+13c
3) both the given expressions are same i.e.
[tex]\dfrac{a-b}{2}[/tex]
4) a+b and 2b
we know that a>b
⇒ a+b>b+b
⇒a+b>2b.
5) both the given expressions are same i.e. 5(a+b) or (a+b)5 since we have to multiply (a+b) and 5.
