b) 16:2 1/3=16:7/3=16*3/7=48/7=6 6/7
c) 18:2 1/4=18:9/4=18*4/9=8

Answer 2

A)
12 : 1 i 1/7 =

= 12 : 8/7=

= 12 * 7/8 = (skracam 12 z 8 --> przez 4)

= 3 * 7/2=

= 21/2=

= 10 i 1/2



b)
16 : 2 i 1/3=

= 16 : 7/3 =

= 16 * 3/7 =

= 48/7 =

= 6 i 6/7



c)
18 : 2 i 1/4=

= 18 : 9/4 =

= 18 * 4/9 = (skracam 18 z 9 --> przez 9)

= 2 * 4/1 =

= 8/1=

= 8



d)
24 : 9 i 3/5= 

= 24 : 48/5 =

= 24 * 5/48 = (skracam 24 z 48 --> przez 24)

= 1 * 5/2=

= 5/2=

= 2 i 1/2
