1/3 : 2 : 1/2 : 1 = 1/3х ÷ 2х ÷ 1/2х ÷ 1х
----------------------------
▪1) найдем среднее арифметическое
( 1/3х+2х+1/2х+1х )÷4 = 11,5
(2/6х+3/6х+3х)÷4=11,5
(3 целых 5/6)х=11,5×4
(3 целых 5/6)х=46
х=46 ÷ (3 целых 5/6) = 46 ÷ 23/6 = 46 × 6/23 = 12
х=12
--------------------------
1/3 × 12 = 4
2 × 12 = 24
1/2 × 12 = 6
1 × 12 = 12
--------------------------
1/3 : 2 : 1/2 : 1 = 4 : 24 : 6 : 12
