x% din 2,5 = 3 , x=?
Explicatie + Rezolvare va rog!

Answer 1

35% × x = 28
35x/100=28
35x=2800
x=2800:35
x=80
 
 x% × 2,5 = 3
2,5x/100 = 3
2,5x=300
x=300:2,5
x=120

Answer 2

35%*x=28
$\frac{35x}{100} =28$
35x=2800
x=2800:35
x=80
---------------------------
x%*2,5=3
$\frac{2,5x}{100} =3$
2,5x=300
x=300:2,5
x=120
