Question

Afla termenul necunoscut : 6×6:b=4. c:64:8=10. (4×2×9):d=8​

Answer 1

Răspuns:

6×6:b=4

36:b=4

b=36:4

b=9

c:64:8=10

c:64=10x8

c:64=80

c=80x64

c=5120

(4×2×9):d=8

(8x9):d=8

72:d=8

d=72:8

d=9

Answer 2

6 × 6 : b = 4

36 : b = 4

b = 36 : 4

b = 9

c : 64 : 8 = 10

c : 64 = 10 × 8

c : 64 = 80

c = 80 × 64

c = 5.120

( 4 × 2 × 9 ) : d = 8

72 : d = 8

d = 72 : 8

d = 9
