17 Află fiecare deîmpărțit necunoscut.
a) x : 5 = 81, rest 4
c)z:7 = 103, rest 1
b) y : 4 = 200, rest 3
d) m: 8 = 0, rest 6​

Answer 1

Raspuns : x=409 , z=722 , y=803 , m=6

d : i = c r => d=i x c + r

x : 5 = 81 , rest 4

x=5 x 81 + 4

x=405 + 4 => x=409

z : 7 = 103 , rest 1

z= 7 x 103 + 1

z=721 + 1 => z=722

y : 4 = 200 , rest 3

y = 4 x 200 + 3

y=800 + 3 => y=803

m : 8 = 0 , rest 6

m= 8 x 0 + 6

m=0+6 => m=6
