1 over 2 added to 2 over 5

1/2 + 2/5 = 5/10 + 4/10 = 9/10

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)
