Answer 1

3 i 1/2: 2 i 2/3= 7/2:8/3= 7/2 * 3/8= 21/16= 1 cała i 5/16

2/3: 1 i 2/5= 2/3: 7/5= 2/3* 5/7=10/21

3/10 : 2 i 3/4= 3/10: 11/4= 33/40

2 i 2/5:1 i 1/4= 12/5 : 5/4= 12/5* 4/5=48/25= 1 cała i 23/25

Zad 8

9/10: 3/8= 9/10* 8/3= 3/5* 4/1= 12/5= 2całe i 2/5

2/5: 3/10= 2/5*10/3= 2/1* 2/3= 4/3 = 1 cała i 1/3

5/6:15/9= 5/6* 9/15= 1/2* 3/3= 3/6= 1/2

8/15:4/5= 8/15* 5/4= 2/3* 1/1= 2/3

2 i 7/9 : 2 i 1/3= 25/9 :7/3= 25/9* 3/7= 25/3*1/7= 25/21= 1 i 4/21

1 i 2/3: 2i 5/6=5/3:17/6= 5/3* 6/17= 5/1* 2/17= 10/17

4 :2i 2/5= 4/1:12/5= 4/1* 5/12= 1/1* 5/3= 5/3= 1 i 2/3

6i 1/8 :7= 49/8 *1/7= 7/8

Answer 2

3 i 1/2 :2 i 2/3=7/2:8/3=7/2 * 3/8 = 21/16

2/3:1 i 2/5=2/3:7/5=2/3*5/7=10/21

3/10:2i3/4=3/10:11/4=3/10*4/11=12/110=6/55

2 i 2/5:1 i 1/4= 12/5:5/4=12/5*4/5=48/25=1 i 23/25

zad.8

9/10:3/8 =9/10 * 8/3 =72/30 =2 i 12/30 = 2 i 2/5

2/5:3/10=2/5*10/3= 20/15=1 i 5/15 = 1 i 1/3

5/6:15/9=5/6*9/15==1/2*3/3=3/6=1/2

8/15:4/5=8/15*5/4=2/3*1/1=2/3

2i7/9:2i1/3=25/9:7/3=25/9*3/7=75/63=1 i 12/63

1 i 2/3:2 i 5/6=5/3:17/6=5/3*6/17=5/1*2/17=10/17

4:2i2/5=4:12/5=4*5/12=1*5/3=5/3=1 i 2/3

6 i1/8:7=49/8*1/7=7/8*1/1 = 7/8
