Question

Oblicz :
C : 1/2 = 4/5
7/8 : P = 5/6

Answer 1

C : 1/2 = 4/5 

C = 4/5 * 1/2

C = 2/5 * 1/1=

C = 2/5


spr.

C : 1/2 = 4/5

L = C : 1/2=  4/5 : 1/2 = 2/5 * 2/1 = 4/5

P = 4/5

4/5 = 4/5

L = P





7/8 : P = 5/6  /*P

7/8 = 5/6 * P /: 5/6

7/8 : 5/6= P

7/8 * 6/5 = P

7/4 * 3/5 = P

21/20 = P

1 i 1/20= P





spr.

7/8 : P = 5/6

L= 7/8 : P = 7/8 : 1 i 1/20 = 7/8 : 21/20= 7/8 * 20/21 = 1/2 * 5/3= 5/6

P = 5/6

5/6 = 5/6

L=P
