Question

Вычислите 1) -7,6+8,9= 2) -8+11,2= 3) 2+(-0,24)= 4) 0,8+(-1,9)= 5) -5 3/4+3 1/2= 6) -2/7+4 1/14= 7) 2 1/7+(-3 3/14)= 8) 6 3/11+(-6 3/11)=

Answer 1

1) -7,6+8,9=1,3
2) -8+11,2=3,2
3) 2+(-0,24)=1,76
4) 0,8+(-1,9)=-0,8
5) -5 3/4+3 1/2=-5 3/4+3 2/4=-2 1/4
6) -2/7+4 1/14=-4/14+3 15/14=3 11/14
7) 2 1/7+(-3 3/14)=2 2/14-3 3/14=-1 1/14
8) 6 3/11+(-6 3/11)=0

Answer 2

Sure, I'll calculate each of the expressions for you:

1) -7.6 + 8.9 = 1.3 2) -8 + 11.2 = 3.2 3) 2 + (-0.24) = 1.76 4) 0.8 + (-1.9) = -1.1 5) -5 + 3/4 + 3 + 1/2 = -1 + 0.75 + 3 + 0.5 = 2.25 6) -2/7 + 4 + 1/14 = -0.2857 + 4 + 0.0714 = 3.7857 7) 2 + 1/7 + (-3 + 3/14) = 2 + 0.1429 + (-3 + 0.2143) = -0.6429 8) 6 + 3/11 + (-6 + 3/11) = 6 + 0.2727 + (-6 + 0.2727) = 0.5454

So the calculations are as follows: 1) -7.6 + 8.9 = 1.3 2) -8 + 11.2 = 3.2 3) 2 + (-0.24) = 1.76 4) 0.8 + (-1.9) = -1.1 5) -5 + 3/4 + 3 + 1/2 = 2.25 6) -2/7 + 4 + 1/14 = 3.7857 7) 2 + 1/7 + (-3 + 3/14) = -0.6429 8) 6 + 3/11 + (-6 + 3/11) = 0.5454

I hope this helps! Let me know if you have any further questions.
