Question

0.25:33(4)=?
cine raspunde are coroana​

Answer 1

Răspuns:

0.25:33(4)=0,0625 sau 1 supra 16

Answer 2

0.25 = 1/4
33.(4) = (334 - 33) / 9 = 301 / 9 (numarul - ce nu e in perioada supra: cate zecimale ai atatia de 9 pui, urmat de : cate cifre intre virgula si perioada atatia de 0)
Aici, daca era 33,0(41) = (33041 - 330) /990
revenind, 0.25 / 33.(4) = (1 / 4) / (301 / 9)
(a / b) : (c / d) = (a / b) * (d / c)
= 1 * 9 / 4 * 301 = 9 / 1204
