Answer 1

a)6/7razy 1 ca 1/2:1 ca 1/3= 6/7 * 3/2 : 4/3 = 18 /14 * 3/4 = 27/28

b)1 ca 3/8:3/4:1ca 2/9= 11/8  * 4/3 : 11/9 = 11/6 * 9/11 = 9/6 = 3/2 = 1 i 1/2

c)1ca 5/6:3ca 2/3razy1ca1/7= 11/6 : 11/3 * 8/7 = 11/6 * 3/11 * 8/7 = 1/2 * 8/7 = 8/14 = 4/7

d)(1/2)do potęgi3 razy2 ca 2/3:1ca 1/6= 1/8 * 8/3 : 7/6 = 1/3 * 6/7 = 2/7

e)1ca 1/4razy6-3:1ca 1/5= 5/4 * 6 - 3 : 6/5 = 15/2 - 3 * 5/6 = 15/2 - 5/2 = 10/2 = 5

f)(4ca 3/8-1 ca 2/3):3 3/4= (35/8 - 5/3) : 15/4 = (105/24 - 40/24) * 4/15 = 65/24 * 4/15 = 13/18

g)2 ca 1/5-1ca 1/6:2ca 1/3= 11/5 - 7/6 : 7/3 = 11/5 - 7/6 * 3/7 = 11/5 - 1/2 = 22/10 - 5/10 = 17/10 = 1 i 7/10

h)[(3/8+1/6):3ca 1/4]-(1/3)do potęgi 3=  [(9/24 + 4/24) : 13/4] - 1/27 = (13/24 * 4/13) - 1/27 = 1/6 - 1/27 = 9/54 - 2/54 = 7/54
