REPEDEEE
DAU COROANA SI 50 PUNCTE​

Answer 1

I oră : x/3 =>rest 2x/3

II oră : 2x/3 • 1/2 = 2x/6 =>noul rest 2x/3 - 2x/6 = x/3

III oră : x/3 • 1/4 = x/12 =>noul rest x/3 - x/12 = x/4

IV oră : x/4 • 1/3 = x/12 =>noul rest x/4 - x/12 = x/6

V oră : 80 mărtișoare

x/3 + x/3 + x/12 + x/12 + 80 = x

4x+4x+x+x+80•12=12x

960=2x

x=480 mărtișoare
