(a + b) / 3 ÷ (a² + b²) / 12 to divide means to multiply by the reciprocal, so we change the division to multiplication and "flip" the second "number": (a + b) / 3 X 12/(a² + b²) the 3 and the 12 reduce leaving a 4 in the numerator, but the a²+b² and the a+b are prime so they do not reduce: 4(a+b) / (a² + b²) that's it! ;).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
