3 1/5 = 3 + 1 / 5 = 3 ∙ 10 / 10 + 2 ∙ 1 / 2 ∙ 5 = 30 / 10 + 2 / 10 = 32 / 10
6 1/2 = 6 + 1 / 2 = 6 ∙ 10 / 10 + 5 ∙ 1 / 5 ∙ 2 = 60 / 10 + 5 / 10 = 65 / 10
- 3 1/5 + ( - 6 1/2 ) = - 3 1/5 - 6 1/2 = - 32 / 10 - 65 / 10 = - ( 32 / 10 + 65 / 10 ) =
- 97 / 10 = - ( 90 + 7 ) / 10 = - ( 90 / 10 +7 / 10 ) = - ( 9 + 7 / 10 ) = - 9 7/10
6 1/2 = 6 + 1 / 2 = 6 ∙ 10 / 10 + 5 ∙ 1 / 5 ∙ 2 = 60 / 10 + 5 / 10 = 65 / 10
- 3 1/5 + ( - 6 1/2 ) = - 3 1/5 - 6 1/2 = - 32 / 10 - 65 / 10 = - ( 32 / 10 + 65 / 10 ) =
- 97 / 10 = - ( 90 + 7 ) / 10 = - ( 90 / 10 +7 / 10 ) = - ( 9 + 7 / 10 ) = - 9 7/10
