Plissss wszystko w załączniku zadanie 14 i 22

Answer 1

Zadanie 14
5/8:3=5/8*1/3=5/24
6:2 1/4=6:9/4=6/1*4/9=24/9=2 6/9=2 2/3
7 1/5:9= 36/5*1/9=36/45=4/5
b) 2/3:3/4=2/3*4/3=8/9
4 3/7:2/3=31/7:2/3=31/7*3/2=93/14=6 9/14
1 1/3:1 3/5= 4/3:8/5=4/3*5/8=20/24=5/6
zadanie 22
4 1/4+ 2 1/3*4 1/2= 4 1/4+ 7/3*9/2= 4 1/4+10 3/6= 4 1/4+10 1/2= 4 1/4+10 2/4= 14 3/4
5 1/7*1 5/9 - 6:4 2/3= 36/7*14/9 - 6: 14/3= 504/63 - 6*3/14= 8 - 18/24 = 7 24/24 - 18/24= 7 6/24= 7 1/4
3 1/4*(2 1/4-1 1/2:6)= 3 1/4* ( 2 1/4- 3/2*1/6)= 3 1/4* (2 1/4-1/4)= 3 1/4*2= 6 2/4=6 1/2
(5 4/9 - 1 1/6) / (3 2/3*(1 1/4-1/2))= (5 8/18-1 3/18) / (3 2/3*( 1 1/4- 2/4))=
=(4 5/18) / (3 2/3* (5/4-2/4))= (4 5/18) / (3 2/3* 3/4)=  (4 5/18) / (2 3/4)= 77/18 : 11/4= 77/18*4/11= 308/198=1 110/198=1 5/9
