Answer 1

3+(-1 1/5)= 3-1 1/5=2 5/5-1 1/5= 1 4/5
2 3/8+(-1/24)= 2 3/8-1/24=2 9/24-1/ 24=
=1 8/24==1 1/3
-12-(-6 1/7)=-12+6 1/7=-11 7/7+6 1/7=-5 1/7
8-у=-7 2/3
-y=-7 2/3-8
-y=-7 2/3-7 3/3
-y=-14 5/3
-y=-15 2/3
y=15 2/3
-7 7/8+(-7 1/16)=-7 7/8-7 1/16=-7 2/16-7 1/16=
=-14 3/16
-5/6+а=-5,6+(-15.3)=-5,6-15.3=-20.9 если а=-15,3
У+(-0,5)=-165
y-0,5=-165
y=-165+0,5
y=-154,5

Calculations

Let's solve the given equations step by step:

1. 3 + (-1 + 1/5) - 3 + (-1 + 1/5) = 3 - 1 + 1/5 - 3 - 1 + 1/5 = 2 + 1/5 - 3 + (-1 + 1/5) = 2 + 1/5

2. 2 3/8 + (-1/24) - 2 3/8 + (-1/24) = 2 3/8 - 1/24 - 2 3/8 + (-1/24) = 2 7/24

3. -12 - (-6 + 1/7) - -12 - (-6 + 1/7) = -12 + 6 - 1/7 - -12 + 6 - 1/7 = -6 - 1/7 - -12 - (-6 + 1/7) = -6 - 1/7

4. 8 - у = -7 + 2/3 - 8 - у = -7 + 2/3 - у = 8 + 7 - 2/3 - у = 15 - 2/3 - у = 14 1/3

5. -7 + 7/8 + (-7 + 1/16) - -7 + 7/8 + (-7 + 1/16) = -7 + 7/8 - 7 + 1/16 - -7 - 7 - 7/8 + 1/16 = -14 - 7/8 + 1/16 - -14 - 7/8 + 1/16 = -14 1/8 + 1/16 - -7 + 7/8 + (-7 + 1/16) = -14 1/8 + 1/16

6. -5/6 + а, if а = -15.3 - -5/6 + (-15.3) = -5/6 - 15.3 - -5/6 - 15.3 = -5/6 - 15 18/30 - -5/6 - 15 18/30 = -15 23/30 - -5/6 + а, if а = -15.3, is equal to -15 23/30

7. У (-0.5) = -165 - у (-0.5) = -165 - у = -165 / (-0.5) - у = 330 - У (-0.5) = -165 is equivalent to у = 330
