POMOCY-ZADANIA Z UŁAMKÓW W ZAŁĄCZNIKU

Answer 1

a) 2i3/4 +1i1/5 *2i3/8 =

     2i3/4 + 6/5 * 19/8 =

     2i3/4 + 3/5 * 19/4 =

     2i3/4 + 57/20 =

     2i15/20 + 57/20 =

     2i72/20 = 5 i 12/20 = 5 i 3/5

 

b)  4i1/6 : 2i3/4 - 5i1/2 = 

      25/6 : 11/4 - 5i1/2 =

      25/6 * 4/11 - 5i1/2 =

      25/3 * 2/11 - 5i1/2=

      50/33 - 5i1/2 =

     1i17/33 - 5i1/2 =

      1i34/66 - 5i 33/66=

      1i34/66 - 4i99/66 = - 3 i 65/66

      

c) 6i1/3 : 2 = 19/3 * 1/2 = 19/6 = 3 i1/6

 

d) 1/3 ; (1/2 + 1/4) =

     1/3 : (2/4 + 1/4) =

     1/3 : 3/4 = 

     1/3 * 4/3 = 4/9
