Answer 1

Răspuns:

a)

8 x n = 72

n = 72 : 8

n = 9

8 x 9 = 72

72 : 9 = 8

72 : 8 = 9

b)

n x 6 = 42

n = 42 : 6

n = 7

7 x 6 = 42

42 : 6 = 7

42 : 7 = 6

c)

36 : p = 9

p = 36 : 9

p = 4

36 : 4 = 9

9 x 4 = 36

36 : 9 = 4

d)

40 : r = 5

r = 40 : 5

r = 8

40 : 8 = 5

40 : 5 = 8

8 x 5 = 40

e)

s : 5 = 8  

s = 8 x 5

s = 40

40 : 5 = 8

40 : 8 = 5

5 x 8 = 40
