Question

Podane ułamki przedstaw w postaci sumy różnych ułamków prostych:

5/6=1/3+1/...

9/20=1/...+1/...

7/12=1/...+1/...

47/60=1/3+1/5+1/...

19/20=1/4+1/...+1/...

11/12=1/...+1/...+1/...

Answer 1

5/6= 2/6 + 3/6  = 1/3 + 1/2

9/20 = 18/40 = 10/40 + 8/40 = 1/4 + 1/5

7/12 = 14/24 = 12/24 + 2/24 = 1/2 + 1/12

47/60 = 20/60 + 12/60 + 15/60 = 1/3 + 1/5 + 1/4

19/20 = 5/20 + 10/20 + 4/20 = 1/4 + 1/2 + 1/5

11/12 = 2/12 + 3/12 + 6/12 = 1/6 + 1/4 + 1/2.
