Question

Sa se afle numetele naturale a,b,c, dacă: a×b=1875,a×c=3125,b+c=200.

Answer 1

$a = \frac{1875}{b} = > b = \frac{1875}{a}$

$a = \frac{3125}{c} = > c = \frac{3125}{a}$

$= > \frac{1875}{a} + \frac{3125}{a} = 200$

$\frac{1875 + 3125}{a} = \frac{200}{1}$

$a = \frac{1875 + 3125}{200}$

$a = \frac{4000}{200}$

$a = 20$

$b = \frac{1875}{20} = 93.75$

$c = \frac{3125}{20} = 156.25$
