MATEMATYKA ;) ŁATWE ;D PILNE.!!!! W ZAŁĄCZNIKU JEST TREŚĆ...

a) sprowadzamy do wspólnego manownika :
3 i 8/40 < 3 i9/40 < 3 i 10/40
3 i 1/5 < 3 i 9/40 < 3 i 1/4
b) - 4 i 8/14 < - 4 i 7/14 < - 4 i 6/14
c) - 2 i 52/65 < - 2 i 15/65 < - 2 i 5/65
tu sobie w tym zadaniu mozesz jeszcze liczby skrocic

a) = 4/6 - 3/6 / 9/12 -8/12 = 1/6 : 1/12 = 1/6 * 12/1 = 2
b) = 42/35 - 10/35 / 6/15 + 10/15 = 32/35 :16/15 = 32/35 * 15/16 = 6/7
c) = 6/4 - 11/4 / 22/12 - 25/12 = - 5/4 : (-3/12) =- 5/4 * (- 12/3) = 15/3 = 5
d) = 5/4 + 27/8 / 21/16 + 3/8 = 10/8 + 27/8 / 21/16 + 6/16 = 37/8 : 27/16 = 37/8 * 16/27 = 74/27
e) = 11/6 - 5/8 / 12/39 - 25/39 = 88/48 - 30/48 / 12/39 - 25/39 = 58/48 : (-13/39)= 58/48 * (- 3/1) = - 58/16= 3 i 5/8
19.
a) = 8 + 5/2 / 9/5 : 14/15 -2 = 16/2 + 5/2/ 9/5 * 15/14 - 2= 21/ 12 / 27/14 - 28/14 = 21/2 : (27/14 - 28/14 ) = 21/2: (-1/14) = 21/2 * (-14/1) = -42
dalej nie mam czasu. ale to na tej samej zaadzie
