Answer:
In a very simple way, it can be verified that the equation is correct by making the divisions that the fractions represent, and checking that the result of these divisions is the same, as presented by the equation.
That is, by making the division of 1/2 and adding it to the division of 3/8, the result of said sum should be equal to 4/10 and 2/5.
Therefore, I will perform this calculation to verify if the equation is correct:
1/2+3/8 =4/10=2/5
0.5 + 0.375 = 0.4
0.875 = 0.4
As we can see, the equation is absolutely false, since the sum of 1/2 + 3/8 does not result in 4/10 or 2/5 (which are the same fraction, but simplified) but 7/8 (7 / 8 = 0.875).
