$Use\ a^2-b^2=(a-b)(a+b).\\\\a^2-b^2=2109\\\\(a-b)(a+b)=2019\\\\(a-b)(a+b)=3\cdot673\to a-b=3\ \wedge\ a+b=673\\\\\underline{+\left\{\begin{array}{ccc}a-b=3\\a+b=673\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad2a=676\qquad\text{divide both sides by 2}\\.\qquad\boxed{a=338}\\\\\text{Put the value of a to the second equation}\\\\338+b=673\qquad\text{subtract 338 from both sides}\\\\\boxed{b=335}\\\\\ \boxed{a=338\ and\ b=335}$

The value of 40÷40.01 is close to 1.

since, when we divide 40 by 40.01 we get the resultant value as: 0.9997500625 ; which is very close to 1.

The value of 4÷40.01 is much less than 1.

since, when we divide 4 by 40.01 we get the resultant value as: 0.09997500625 ; which is much less than 1.

The value of 4000÷40.01 is much greater than 1.

since, when we divide 4000 by 40.01 we get the resultant value as: 99.97500625 ; which is much greater than 1.
