Oblicz:
2 i 5/6 : 3/4
= 17/6 razy 4/3
= 17/3 razy 2/3
= 34/9
= 3 i 7/9
3/5= 6/10=0,6 więc 0,4<3/5
3/4=75/100=0,75 więc 0,7<3/4
7/25= 28/100=0,28 więc 0,3>7/25
1,75= 1 i 75/100= 1 i 3/4 więc 1,75=1 i 3/4
1,8> 1 i 8/13
5 i 1/8= 5,125 więc 5,12<5 i 1/8
0,8=8/10 więc 8/9>8/10
3 i 9/20= 3 i 45/100= 3,45 więc 3 i 9/20=3,45
8 i 1/4=8,25 więc 8,3> 8 i 1/4
2 i 5/6 : 3,4 = (2*6 +5)/6 : 34/10 = 17/6 : 17/5 = 17/6 * 5/17 = 5/6
