Question

72.
Află numărul necunoscut:
24 : 3 x a = 8 x 9
7 x 8: n = 12:6
49:3x6 = 84 : 2
3 x 2 xg= 72
42 : 7 x z= 48
5 x 6: X= 2
b)
944 : X=4
Xx8 = 192
456 : X = 6
X:4= 69 r 3
X:8=98 r1
X:6 = 136 r 3
427 :X= 4r3
967 :X = 8r7
879 : X=6r3
Numa primu va rog

Answer 1

Explicație pas cu pas:

24 : 3 x a = 8 x 9

8 x a = 72

72 : 8 = 9

a = 9

7 x 8: n = 12:6

56 : n = 2

n = 56 : 2

n = 28

49:3x6 = 84 : 2

96 = 21

3 x 2 x g= 72

6 x g = 72

72 : 6 = g = 12

42 : 7 x z= 48

6 x z = 48

48 : 6 = z = 8

5 x 6: X= 2

30 : X = 2

30 : 2 = X = 15

944 : X=4

944 : 4 = 236

X x 8 = 192

192 : 8 = 24

456 : X = 6

456 : 6 = 76

X:4= 69 r 3

69 x 4 = 276

X:8=98 r1

98 x 8 = 768

X:6 = 136 r 3

136 x 6 = 816

427 :X= 4 r 3

427 : 4 = 106 r 75

967 :X = 8 r 7

967 : 8 = 120 r 875

....?

879 : X=6r3

879: 6 = 146 r 5

X:8=98 r 1

98 x 8 = 882

X:6 = 136 r 3

136 x 6 = 816

427 :X= 4r3

427 : 4 = 106 r 75

879 : X=6r3

879:6 = 146 r 5

sorry I don't really know these ones with rest
