Question

x : (2+1/5 : 3/10) = (1 - 2/3 .9/8) : ( 3 - 1/4)

(3/4 + 1/2 + 5/6) : x = x : (1 +11/6)

Answer 1

x:(2 + 1/5 * 10/3) = (1 - 2/3 * 8/9) : (23/4)

X:(2 + 2/3) = (1 - 16/27) : 11/4

x:(8/3) = 11/27 * 4/11

x:(8/3) = 4/27

x * 3/8 = 4/27  /: 3/8

x = 4/27 * 3/8

x = 32/81

To jest pierwszy przykład.

 

(3/4 + 1/2 + 5/6) :x=x: 17/6

(9/12 + 6/12 + 10/12) :x=x * 6/17

(25/12) :x=x * 6/17

12/25 * x=x * 6/17

Dalej nie wiem :(...
