Question

Afla numarul necunoscut: 9•4:a=6. 6•4:b=8 c:5•4=8. n:(3•3)=6•4. (13+o):8=7. 33-p•4=13 d•3:6=4. m:(2•4)=14:2.

Answer 1

Răspuns:

Explicație pas cu pas:

9•4:a=6.

36 : a = 6

a = 36 : 6 = 6

______________

6•4:b=8

24 : b = 8

b = 24 : 8 = 3

______________

c:5•4=8.

c : 20 = 8

c = 20•8 = 160

_____________

n:(3•3)=6•4.

n : 9 = 24

n = 9•24 = 216

______________

(13+o):8=7.

13 + o = 8•7

13 + o = 56

o = 56 - 13 = 43

_______________

33-p•4=13

p•4 = 33 - 13 = 20

p = 20 : 4 = 5

_______________

d•3:6=4.

d•3 = 6•4 = 24

d = 24 : 3 = 8

________________

m:(2•4)=14:2.

m : 8 = 7

m = 8•7 = 56
