Question

вычислите: -2,4+3 1/3-(-2,6)=
ребятушки,помогите пожалуйста!!!

Answer 1

1)-2,4+3 1/3=-24/10+10/3=(-72+100)/30=28/30
2)28/30-(-2,6)=28/30+2,6=28/30+26/10=28/30+78/30=106/30=3 16/30=3 8/15

Answer 2

- 2,4 + 3 1/3 - ( - 2,6 ) = 3 8/15
1) - 2,4 + 3 1/3 = - 24/10 + 10/3 = - 72/30 + 100/30 = 100/30 - 72/30 = 28/30 = 14/15
2) 14/15 - ( - 2,6 ) = 14/15 - ( - 26/10 ) = 28/30 - ( - 78/30 ) = 28/30 + 78/30 = 106/30 = 3 16/30 = 3 8/15
