Answer 1

4 4/7 : 2 2/3 = 32/7:8/3=32/7*3/8=12/7=1 i 5/7



1 2/9 * 2 3/11 = 11/9*25/11=25/9=2 i 7/9



5 3/5 : 1 1/7 = 18/5:8/7=18/5*7/8=63/20=3 i 3/20



Oblicz :



6 1/2 - 5/6 = 3/6-5/6=-2/6=-1/3

6 1/2 + 1/2 = 7

6 1/2 - 3/4 = 6 i 2/4-3/4=5 i 6/4-3/4=5 i 3/4

6 1/2 + 1/3 = 3/6+2/6=5/6

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