25 : b = 6  /*b

25 = 6 * b  /: 6

25 : 6 = b

25/6= b

4 i 1/6 = b


spr.

25 : b= 6

L = 25 : b = 25 : 4 i 1/6 = 25 : 25/6= 25 * 6/25= 1 * 6/1= 6/1= 6

P = 6

L=P




d : 4= 5 i 1/2

d= 5 i 1/2 * 4

d= 11/2 * 4

d= 11/1 * 2

d= 22/1

d= 22


spr

d : 4= 5 i 1/2

L = d : 4= 22 : 4= 22 * 1/4= 22/4 = 5 i 2/4= 5 i 1/2

P = 5 i 1/2

5 i 1/2 = 5 i 1/2

L=P
