Question

Cu ce procent a crescut nr de piese daca in 2002 erau 50.000.000 iar in 2012 erau 55.000.000 .Vreau rezolvare completă urgent!!!

Answer 1

55000000 - 50000000 = 5000000
$\frac{x}{100}$ × $\frac{50000000}{1}$ = $\frac{5000000}{1}$
$\frac{50000000x}{100}$ = 5000000
500000x = 5000000
x = 5000000 ÷ 500000
x = 10
