5.375+3.2 = 8.575, or 8 23/40. LCD is 40.
The terms which are in both numerator and denominator will be cancelled out as there is not exponents involved so the result will be a/e
Further explanation:
We have to evaluate the expression
Given expression is:
We can also write the expression as:
The terms that are both in numerator and denominator will be cancelled out.
So the final expression will be:
The terms which are in both numerator and denominator will be cancelled out as there is not exponents involved so the result will be a/e
