Explicație pas cu pas:

Answer 2

a)

x : 25 = 11 => x = 11 x 25 = 275

x : 10 = 45 => x = 45 x 10 = 450

x : 63 = 10  => x = 10 x 63 = 630

b)

x : 6 = 100 => x = 100 x 6 = 600

x : 100 = 9 => x = 9 x 100 = 900

x : 7 = 100 => x = 100 x 7 = 700

c)

x : 10 : 6 = 4 => x = 4 x 6 x 10 = 24 x 10 = 240

x : 100 : 2 = 3 => x = 3 x 2 x 100 = 6 x 100 = 600

x : 11 : 7 = 9 => x = 7 x 9 x 11 = 63 x 11 = 693
