Найдите неизвестное. 72: х=24:3 11х=22•4 12:х=96:16 18х=72•5 Х:56=28:14 х:20=20:4

Answer 1

х=72*3/24=9
х=22*4/11=8
х=12*16/96=2
х=72*5/18=20
х=56*28/14=112
х=20*20/4=100

Answer 2

=
72 : х = 8
8х = 72
х = 9
-------------------
=
11х = 88
    х = 8
------------------
= 
12 : х = 6
6х = 12
  х = 2
-------------------
=
18х = 360
    х = 20
-------------------
=
х : 56 = 2
х = 56*2
х = 112
-------------------
=
х : 20 = 5
х = 5 * 20
х = 100
