Proszę o napisanie obliczeń (bardzo potrzebne)

Answer 1

(-1/4)+(-1/2) + 1/8 + (-5/4) + (3/8) + (+1,5) + (-7/8)= -0,25-0,5+1,125-1,25+0,375+1,5-0,875=0,125

5,75 + (-8,5) + (-4/5) + (+10,7) + (-0.31) + (-3/4)= =5,75-8,5-0,8+10,7-0,31-0,75=6,09

6,5 + (-0,025) + (0,025) + (-9/2) + (-0,05) + (1,2)= 6,5-0,025-4,5-0,05+1,2=3,125

Answer 2

(-1/4)+(-1/2) + 1/8 + (-5/4) + (3/8) + (+1,5) + (-7/8) = (-¼)+ (-2/4) + 1/8 + (-5/4) + (3/8) + (+1,5) + (-7/8) =(-¾)+⅛(-⅘)+3/8+ 1i5/10= (-6/8)+⅛+(-⅘)+3/8+ 1i5/10= (-⅝)+(-⅘)+3/8+ 1i5/10=(-25/40)+(-32/40)+15/40+1i5/10=(-57/40)+15/40+1i20/40=(-42/40)+1i20/40=1i22/40

5,75 + (-8,5) + (-4/5) + (+10,7) + (-0.31) + (-3/4) =-2,75+(-4/5) + (+10,7) + (-0.31) + (-3/4) =-7,25+10,7+(-0,31)+(-0,75)= 3,45+(-0,31)+(-0,75)=3,14+(-0,75)=2,39

6,5 + (-0,025) + (0,025) + (-9/2) + (-0,05) + (1,2)= 6,475+(0,025) + (-9/2) + (-0,05) + (1,2)=6i5/20+(-9/20) + (-0,05) + (1,2)= 6i14/100+(-5/100)+1,2=6i9/100=1,2=6,09+1,2=7,59

Answer 3

(-1/4)+(-1/2) + 1/8 + (-5/4) + (3/8) + (+1,5) + (-7/8)=-3/4+(-9/8)+1,5=-3/8
5,75 + (-8,5) + (-4/5) + (+10,7) + (-0.31) + (-3/4) =-11/4+956/100=691/100=6 91/100
6,5 + (-0,025) + (0,025) + (-9/2) + (-0,05) + (1,2) =6,475+(-4,475)+(-0,05)=1,95
