Помогите сделать вычисления развернуто.-3 1/7+(-1 3/14)=-1 2/5+(-2,8)=-1 1/3+(-2,25)=

-3 1/7+(-1 3/14)= - 3 1/7 - 1 3/14 = - 24/7 - 17/14 = - 48/14 - 17/14 = - (48+17)/14 = 65/14 = - 4 9/14 -1 2/5+(-2,8)= - 1 2/5 - 2 8/10 = - 7/5 - 28/10 = - 14/10 - 28/10 = - (14 + 28)/10 = - 42/10 = - 4 2/10 = - 4 1/5 -1 1/3+(-2,25)= - 1 1/3 - 2 25/100 = - 1 1/3 - 2 1/4 = - 4/3 - 9/4 = - 16/12 - 27/12 = - (16 + 27)/12 = - 33/12 = - 2 3/4
