I am thinking of a fraction. The sum of the denominator and numerator is 19. When I take away 5 from the numerator, it can be simplified to $$\frac{2}{5}$$. <hr> What fraction am I thinking of? <br> $$\frac{A}{B}$$ <hr>A: <input min="0" type="number" class="lineinput" placeholder="?" /> B:<input min="0" type="number" class="lineinput" placeholder="?" />
