The statement “$x$ is greater than $140\%$ of $y$” is equivalent to an inequality, and translates to $x \gt 1.4y$.

The statement ”$x$ is $200\%$ greater than $y$” translates to $x$ exceeds $y$ by $200\%$ of $y$ and is an equality. This statement would algebraically translate to $x = y + 200\%y = y+2y=3y$.

These statements can be confusing, because of the subtle differences in language.

Could you please tell the difference between ”X is greater than 140% of y” and ”X is 200% greater than y”?
