Answer 1

5 i 5/9 * d * 2 = 5 i 1/3

50/9 * d * 2 = 16/3

50/9 * 2 * d= 16/3

100/9 * d= 16/3 

d= 16/3 : 100/9

d= 16/3 * 9/100

d= 4/1 * 3/25

d= 12/25


spr.
5 i 5/9 * d * 2 = 5 i 1/3

L = 5 i 5/9 * d * 2= 50/9 * 12/25 * 2= 2/3 * 4/1 * 2 = 16/3= 5 i 1/3

P = 5 i 1/3

5 i 1/3 = 5 i 1/3

L=P




9 i 3/5 : g = 4 i 1/5    /* g

9 i 3/5 = 4 i 1/5 * g   /: 4 i 1/5

9 i 3/5 : 4 i 1/5= g

48/5 : 21/5 = g

48/5 * 5/21 = g

16/1 * 1/7= g

16/7 = g

2 i 2/7 = g


spr.

9 i 3/5 : g = 4 i 1/5

L = 9 i 3/5 : g= 9 i 3/5 : 2 i 2/7  = 48/5  : 16/7 = 48/5 * 7/16= 3/5 * 7/1 = 21/5= 4 i 1/5

P = 4 i 1/5

4 i 1/5 = 4 i 1/5

L=P
