Proszę na jutrooo .! :*

Answer 1

A) 3,375+4 1/6-2 2/3=3375/1000+25/6-8/3=10125/3000+12500/3000-8000/3000=14625/3000=4,875
b) 10 2/3-4 7/8+5/6=32/3-39/8+5/6=256/24-117/24+20/24=159/24=6,625
c) 5,25-2 2/3-1 5/6=525/100-8/3-11/6=1575/300-800/300-550/300=225/300=0,75
d) 4,5+6 3/4-(12-5 3/8)=45/10+27/4-(12/1-43/8)=45/10+27/4-(96/8-43/8)=45/10+27/4-53/8=180/40+270/40-265/40=185/40=4,625
e) 8 1/2-1,75-(1 3/4+1 2/3)=17/2-175/100-(7/4+5/3)=17/2-175/100-(21/12+20/12)=17/2-175/100-41/12=2550/300-525/300-1025/300=1000/300=3 1/3
f) 4 5/6+2,5-3 2/3+5 1/12=29/6+25/10-11/3+61/12=290/60+150/60-220/60+305/60=525/60=8,75

Answer 2

A) 3 3/8+ 4 1/6- 2 2/3= 3 9/24+ 4 4/24- 2 16/24= 5 21/24
b) 10 2/3- 4 7/8+5/6 =10 16/24- 4 21/24+20/24= 6 15/24
c)5,25 -2 2/3 - 1 5/6=5 3/12- 2 8/12- 1 10/12= 9/12
d)4,5 +6 3/4 - (12-5 3/8) =4,625
e) 8 1/2 - 1,75 - (1 3/4 + 1 2/3)=8 6/12-1 9/12- 3 5/12= 3 4/12=3 1/3
f)4 5/6+2,5-3 2/3 +5 1/12=4 10/12+ 2 6/12 - 3 8/12 + 5 1/12= 8 9/12

Mam nadzieje, że tym razem dasz mi naj :P
