7-3⅓-2⅛=

3¾-2⅔+6-3⅚=

10-(2¹/₉-½+1⅚)=

Answer 1

4⅓-2⅖+1⅕=  4 5/15 - 2 6/15 + 1 3/15 = 4 5/15 -  3 9/15 =

=3 20/15 - 3 9/15 = 1/15

4⅓-2⅖+1⅕=

7-3⅓-2⅛=6 24/24 – 3 8/24 – 2 3/24 = 3 16/24 – 2 6/15 = 1 13/25

3¾-2⅔+6-3⅚=3 9/12 – 2 8/12 + 5 12/12 – 3 10/12= 1 1/12 + 2 2/12= 3 3/12

= 3 1/4

10-(2¹/₉-½+1⅚)=10 -(2 2/18 – 9/18 + 1 15/18 )= 10 – (1 20/18-  9/18 +1 15/18 )= 10- (1 11/18+1 15/18) = 10 - 2 26/18 = 9 18/18 - 2 26/18 = 9 18/18 -3 8/18 = 6 10/18 = 6 5/9

Answer 2

4⅓-2⅖+1⅕= 4 5/15 - 2 6/15 + 1 3/15 = 4 5/15 - 3 9/15 = =3 20/15 - 3 9/15 = 1/15 4⅓-2⅖+1⅕= 7-3⅓-2⅛=6 24/24 – 3 8/24 – 2 3/24 = 3 16/24 – 2 6/15 = 1 13/25 3¾-2⅔+6-3⅚=3 9/12 – 2 8/12 + 5 12/12 – 3 10/12= 1 1/12 + 2 2/12= 3 3/12 = 3 1/4 10-(2¹/₉-½+1⅚)=10 -(2 2/18 – 9/18 + 1 15/18 )= 10 – (1 20/18- 9/18 +1 15/18 )= 10- (1 11/18+1 15/18) = 10 - 2 26/18 = 9 18/18 - 2 26/18 = 9 18/18 -3 8/18 = 6 10/18 = 6 5/8

 

na końcu raczej ma być 8 a nie 9
