a.) 6,5 : ( 2 i 1/4 *6-0,5)= 6,5 : ( 2 i 1/4 * 5 i 1/2)= 6,5 : 12 i 3/8= 52/99
b.)(5- 1i 1/2) : (2 i 3/8 -1,75)=3 i 1/2 : (2 i 3/8 - 1 i 3/4)= 3 i 1/2 : (2 i 3/8 - 1 i 6/8)= 3 i 1/2 : (1 i 11/8 - 1 i 6/8)= 3 i 1/2: 5/8= 7/2 * 8/5= 28/5= 5 i 3/5
c.)5/7 * 4,2-( 1i 1/4 - 0,5)= 5/7 * 4,2 - (1 i 1/4 - 1/2)= 5/7 * 4,2- (5/4 - 2/4)= 5/7 * 4,2 - 3/4= 5/7 *42/10 - 3/4= 3 - 3/4= 2 i 1/4
d.)3i 3/4 * 0,8+2 i 2/3* 0,3= 3 i 3/4 * 8/10 + 2 i 2/3 * 3/10= 15/4 * 8/10 + 8/3 *3/10= 3 + 4/5= 3 i 4/5
e.)4,5 -2,4 : 2 i 2/3 + 1,4=2,1: 2 i 2/3+ 1 i 4/10= 2,1: 2 i 20/30 + 1 i 12/30= 2,1 : 3 i 32/30 = 2,1 : 4 i 2/30= 2 ,1 : 4 i 1/15= 21/10: 61/15= 21/10 * 15/61= 63/122
a) 6,5:(2i1/4 *6-0,5)=6,5:(2i1/4 * 5,5)= 6,5: (2,25*5,5 ) = 6,5:12,375 = 0,5252....
b) (5-1i1/2):(2i3/8 - 1,75)= (5-1,5):(2,375-1,75)=3,5:0,625=5,6
c)5/7 *4,2-(1i1/4-0,5)=5/7*4i2/10-(1i1/4-1/2)=5/7*42/10-(5/4-1/2)=210/70-(5/4-2/4)=3-(5/4-2/4)=3-3/4= dalej nie wiem :)
