rozwiąż równanie i sprawć rozwiązanie:
12 *a=13 1/3
b:4 1/2=2 2/3
2 5/6:c=41/4
2 2/5*d=9
prosze o jak najszybszą odpowiedz pilne daje naj za najszybszą odpowiedz!!!!!! :)

12 *a=13 1/3
12a = 40/3
a = 40/3 : 12
a = 40/3 * 1/12
a = 10/9
spr 12 * 10/9 = 120/9 = 13 3/9 = 13 1/3 - L
13 1/3 - P czyli L = P
b:4 1/2=2 2/3
b : 9/2 = 8/3
b * 2/9 = 8/3 /(*9)
2b = 24 /:2
b = 12
spr 12 : 9/2 = 12 * 2/9 = 24/9 = 2 6/9 = 2 2/3 -L
2 2/3 - P czyli L=P
2 5/6:c=41/4
17/6 :c = 10,25 /*c
17/6 = 10,25c /*6
17 = 61,50c
17 = 123/2c /*2
34 = 123c
c = 34/123
spr 17/6 :34/123 = 17/6 * 123/34 = 123/12 = 10 3/12 = 10 1/4- L
41/4 - 10 1/4 - P czyli L=P
2 2/5*d=9
12/5d = 9 /*5
12d = 45 /:12
d = 45/12
d = 15/4
spr 12/5 * 15/4 = 9 - L
9 - P czyli L=P
