Question

Câu 2: Tìm x biết:

a)2/9  + x = 1                                                                 b) x :  7/11= 22

Answer 1

a x = 1 - 2/9

   x = 7/9

b x = 22 x 7/11

  x = 14

Answer 2

a, \(\Leftrightarrow x=1-\dfrac{2}{9}=\dfrac{7}{9}\)

b, \(\Leftrightarrow x=\dfrac{22.7}{11}=2.7=14\)

Answer 3

Câu 2: Tìm x biết:

a)2/9  + x = 1                                        

  =1-2/9

=9/9-2/9

=>7/9           

    b) x :  7/11= 22    

=22*7/11

=14                                             

Answer 4

a x = 1 - \(\dfrac{2}{9}\)

x = \(\dfrac{7}{9}\)

b x = 22 x \(\dfrac{7}{11}\)

x = 14
