Dar la fractia 123 pe 1000?
r.................

Doar raspuns, dau coroana

Answer 1

x + 2017/10000 = 10000/10000

x = 10000/10000 - 2017/10000

x = 7983/10000

y + 123/1000 = 1000/1000

y = 1000/1000 - 123/1000

y = 877/1000

Answer 2

2017/10000 + x = 1 sau 10000/10000

x = (10000-2017)/10000

x = 7983/10000

123/1000 + x = 1000/1000

x = (1000-123)/1000

x = 877/1000
