#### Answer

$True$

#### Work Step by Step

$\frac{14}{19}+\frac{5}{19}=\frac{19}{19}=1$, and 1 is an element of the natural numbers, so that means the first statement is true.
$12\times(50)^{2}\times(50+10)-12\times(50+10)\times(50)^{2}=0$
$30000\times60-720\times2500=0$
$1800000-1800000=0$
$0=0$, the second statement is also true.
Since both of the statements are true, the answer is $true$.
