2 3/4-1 2/3

4 1/3-5/6

c) 8 3/4-2 1/8

4 4/5-1 1/7

8 1/2-6 5/7

Answer 1

a) 6/7-5/6=36/42 - 35/42= 1/42

b)2 ¾-1⅔= 2 i 9/12 - 1 i 8/12 = 1 i 1/12

c)4 ⅓-⅚= 4 i 2/6 - ⅚ = 3 i 8/6 -⅚=3 ⅜

d) 8 ¾-2⅛=8 i 6/8 -2⅛= 6 ⅞

e)4 ⅘-1 1/7= 4 i 28/35 - 1 i 5/7 = 3 i 23/35

f)8 ½-6 i  5/7= 8 i 7/14 - 6 i 1-/14 = 2 i 6/14= 2 i 3/7

Answer 2

Wykonaj odejmowanie.

b) 6/7-5/6 = 36/42 - 35/42 = 1/42

 

2 3/4-1 2/3 = 11/4 - 5/3 = 33/12 - 20/12 = 13/12 = 1  1/12

4 1/3-5/6 = 13/3 - 5/6 = 26/6 - 5/6 = 21/6 = 3 3/6 = 3  1/2

c) 8 3/4-2 1/8 = 35/4 -17/8 = 70/8 - 17/8 = 53/8 = 6 5/8

4 4/5-1 1/7 = 24/5 - 8/7 = 168/35 - 40/35 = 128/35 = 3 23/35

8 1/2-6 5/7 = 17/2 - 47/7 = 119/14 - 94/14 = 25/14 = 1 11/14
