Work Step by Step

$\frac{2}{5}$+$\frac{3}{5}$ =$\frac{5}{5}=1$, and 1 is an element of the natural numbers, which means the first statement is true. For the second statement, plug in 100. $9\times(100)^{2}\times(100+11)-9\times(100+11)\times(100)^{2}=0$ $90000\times111-999\times10000=0$ $9990000-9990000=0$ $0=0$, the second statement is also true. Since both of the statements are true, the answer is $True$.
