zadanie 16 

a) =2,75+ 5,5= 8,25

=3 i 2/5+ 6 i 1/2= 3 4/10 + 6 5/10= 9 9/10

=2 1/8 + 1 1/8= 3 2/8 = 3 1/4

= 2/10 + 3 1/6 = 6/30+ 3 5/30 = 3 11/30

 

b) = 1 1/3 +1/4= 1 4/12 +3/12= 1 7/12

=2 73/100 + 9 2/3= 2 219/300 + 9 200/300 = 11 419/300 = 12 119/300

=7/100 + 10 3/10= 7/100 + 10 30/100= 10 37/100

= 4 5/9 + 1 1/2= 4 10/18 + 1 9/18= 5 19/18= 6 1/18

a)= 4 2/10 - 2/5= 4 2/10 - 4/10= 3 8/10 = 3 4/5

=5 2/5 - 0,25= 5 8/20 - 5/20 = 5 3/20

=0,9- 0,375=  0,525

 

b) =3 3/4 - 1 1/6= 3 18/24 - 1 4/24= 2 14/24= 2 7/12

=  4 2/3 - 1 1/2 = 4 4/6 - 1 3/6= 3 1/6

= 6 1/7 - 2 2/5= 6 5/35 - 2 14/35= 3 28/35
