Answer 1

b) 1/5 - 1/10 = 1/10-1/10 = 0

7/8 - 15/32 = 28/32 - 15/32 = 12/32= 6/16= 3/8

6 i 1/5 - 1/4 = 6 i 4/20 - 5/20 = 5 i 24/20 - 4/20 = 5 i 20/20 = 6

4 i 8/9 - 3 i 1/3 = 4 i 24/27 - 3 i 9/27 = 1 i 15/27 = 1 i 5/7

c) 2/3 * 5/6 = 1/3 * 5/3 = 5/9

14 * 5/7 = 14/1 * 5/7 = 2/1 * 5/1 = 7/1 = 7

6 * 2 i 2/3 = 6/1 * 8/3 = 2/1 * 8/1 = 16/1 = 16

1 i 3/4 * 2 i 1/5 = 7/4 * 11/5 = 77/20 = 3 i 17/20

d)4/5 :12 = 4/5 * 1/12 = 1/5 * 1/3 = 1/15

5 i 2/9 : 3 = 47/9 * 1/3 = 47/27 = 1 i 20/27

15:2 i 3/8 = 15/1 * 8/19 = 120/19 = 6 i 6/19

7/10 : 5/14 = 7/10 * 14/5 = 7/5 * 7/5 = 49/25 = 1 i 24/25

 

Trochę tego dużo więc ja pózniej chyba resztę rozwiążę ;)

O miałam właśnie robić resztę, dzieki cat22

 

 

Answer 2

ja chyba dokoncze reszte przykladow...?

 

15:2 3/8 = 15:19/8 = 15/1x8/19 = 120/19 = 6 i 6/19

 

7/10:5/14 = 7/10x14/5 = 49/25 = 1i24/25

 

8/15:3 1/3 = 8/15:10/3 = 8/15x3/10 = 4/25

 

8 2/5:13/15 = 42/5x15/13 = 126/13 = 9 9/13

 

1 5/6:1 1/10 = 11/6:11/10 = 11/6x10/11 = 10/6 = 1 4/6 = 1 2/3

 

 2 3/4:3 2/3 = 11/4:11/3 = 11/4x3/11 = 3/4
