1. ## Help please

If $a,b$ and $c$ are whole positive numbers, prove that
$\frac{a}{b+c}+\frac{b}{a+c}+\frac{c}{a+b}\ge\frac{ 3}{2}$

2. You could argue that for $a=b=c=1$ the value of the expression is $\frac{3}{2}$ and that the expression is strictly increasing with respect to each unknown.

3. iknowone I agree with you but still I can't understand how to solve it. Note that I am at the sixth grade so I think that there's something simpler.

4. Somebody just told me that there are 8 different ways of solving this inequality.
Is that .................................................. .......true??????????
