prosze o dzialania bo musze je napisac

Answer 1

a)53/10 -14/5 -7/4=106/20-56/20-35/20=15/20

b)77/6 -32/3+38/5=13/6+38/5 =65/30+204/30=269/30

c)36/35 -25/35-5/35=6/35

d)63/10+19/5-17/5 +7/2=67/10+35/10=102/10

e)61/6-(51/4 -47/6)-7/2=40/6-(153/12-94/12)=80/12-59/12=21/12

f)7/4 +1987/20-447/5-3/2=1/4+1987/20-1788/20=5/20+199/20=204/20

Answer 2

a) 5 3/10 - 2 4/5 - 1 3/4  = 4 i 13/10 - 2 i 8/10 - 1 i 3/4 = 2 i 5/10 - 1 i 3/4 = 2 i 1/2 - 1 i 3/4 = 2 i 2/4 - 1 i 3/4 = 1 i 6/4 - 1 i 3/4 = 3/4

 

b)12 5/6 - 10 2/3 + 7 3/5  = 12 i 5/6 - 10  i4/6 + 7 i 3/5 = 2 i 1/6 + 7 i 3/5 = 2 i 5/30 + 7 i 18/30 = 9 i 23/30

 

c)36/35 - 5/7 - 5/35 = 36/35 - 25/35 - 5/35 = 11/35 - 5/35 = 6/35

 

d)6 3/10 + 3 4/5 - 3 2/5 + 3 1/2  = 5 i 13/10 + 2/5 + 3 i 5/10 = 8 i 18/10 + 4/10 = 8 i 22/10 = 10 i 2/10 = 10 i 1/5

 

e)10 1/6 - (12 3/4 - 7 5/6 ) - 3 1/2 = 10 i 1/6 - (12 i 9/12 - 7 i 10/12) - 3 i 1/2 = 10 i 1/6 - (11 i 21/12 - 7 i 10/12) - 3 i 3/6 = 9 i 7/6 - 4 i 11/12 - 3 i 3/6 = 9 i 14/12 - 4 i 11/12 - 3 i 6/12 = 5 i 3/12 - 3 i 6/12 = 4 i 15/12 - 3 i 6/12 = 1 i 9/12 = 1 i 3/4

 

f)1 3/4 + (99 7/20 - 89 2/5) - 1 1/2 = 1 i 3/4 + (98 i 27/20 - 89 i 8/20) - 1 i 1/2 = 1 i 3/4 + 9 i 19/20 - 1 i 1/2 = 1 i 15/20 + 9 i 19/20 - 1 i 10/20 = 10 i 34/20 - 1 i 10/20 = 9 i 24/20 = 10 i 4/20 = 10 i 1/5
