Question

10 p 5) Aflati valoarea numarului necunoscut a) 5 981 + a = 10 000 c) p-439 = 35 b) n:9=81 d) 333 * m= 3 )​

Answer 1

Răspuns:

a) 5981+a=10000

a=10000-5981=4019

b) n:9=81

n=81×9

n=729

c) p-439=35

p=35+439

p=474

d) 333×m=3

m=3/333=1/111

Answer 2

$\bold{a)} \ 5 \ 981+a=10 \ 000 \\ \Rightarrow \ a=10 \ 000-5 \ 981=\boxed{4 \ 019}; \\ \bold{c)} \ p-439=35 \\ \Rightarrow p =35+439=\boxed{474}; \\ \bold{b)} \ n:9=81 \\ \Rightarrow n=81\cdot 9=\boxed{729}; \\ \bold{d)} \ 333 \cdot m=3 \\ \Rightarrow \ m=\frac{3}{333}=\boxed{\frac{1}{111}}.$
