We are given equation:
.
We need to explain if the given equation is true or not.
If true, then why true and if not true, why not.
We can see than we have 1/3 on left side of the equation.
And fraction 1/5 is being added into 1/3 on left side of the equation.
On right side of equation we have 1/4.
We know, 1/3 is greater than 1/4.
And if we add something into 1/3, it would also greater than 1/4.
Therefore, 1/4 is less than 1/3+1/5.
Those can not be equal.
Therefore, correct option is 4th option.
Because 1/4 < 1 /3, this equation can not be true.
