⅗-(1,4*5/14-0,9):(-⅕)

----

3²

4/5:(1/2-1/5)-(2/3-(3/8-1 1/3 ))

Answer 1

=⅗-(14/10*5/14-9/10):(-⅕)      ⅗-(½-9/10):(-⅕)     ⅗-(5/10-9/10):(-⅕)       

---------------------------------- = --------------------- =  -------------------------  =

                  9                                 9                             9

     ⅗-(-⅘*5/1)      ⅗+4/1       ⅗+20/5     

= ---------------- = --------- = ------------ = ⅘*1/9=4/45

              9              9               9

 

 

=   ⅘:(5/10-2/10)-(⅔-(9/24-32/24))=(⅘:3/10)-(⅔-(-23/24))=(⅘*10/3)-(⅔+23/24)=

=8/3-(16/24+23/24)=8/3-39/24=64/24-39/24=25/24=1 i 1/24
