Question

Rezolvati in multimea numerelor rationale ecuatiile:
a) 14,7•x=2,94;
b) x•838,32=1257,48;
c) x:7,4=5,6;
d) 23,576:x=29,47.
Cat mai repede va rog

Answer 1

a)14,7•x=2,94
x=2,94:14,7
x=0,2
V:4,7•0,2=2,94

b)x•838,32=1257,48
x=1267,48:838,32
x=1,5
V:1,5•838,32=1257,48


c)x:7,4=5,6
x=5,6•7,4
x=41,44
V:41,44•7,4=5,6


d)23,576:x=29,47
x=23,576:29,47
x=0,8
V:23,576:0,8=29,47
Succes!
