Answer 2

$\frac{AP}{PB}= \frac{2}{5}$ ⇒ AB $= \frac{5AP}{2}$

AP+PB = AB
AP + 1 = $= \frac{5AP}{2}$
1 = $= \frac{5AP}{2}$ - AP
1 = $\frac{5AP-2AP}{2}$
1 = $\frac{3AP}{2}$
AP =$\frac{2}{3}$

AB = AP + PB 
AB = 1 + $\frac{2}{3}$
AB = $\frac{3+2}{3}$
AB = $\frac{5}{3}$


Poti sa verifici , e corect . Multa bafta!
