1 over 2 added to 2 over 5 For this case, the first thing we must do is rewrite the expression: (1/2) + (2/5) Now add the fractions taking into account the cross product: (1/2) + (2/5) = ((5) + (4)) / (10) = Finally, we add the values that are in the numerator to obtain the final result: (9/10) Answer: (1/2) + (2/5) = (9/10)
