Answer 2

1) 20/28+7/28=27/28

2) 8/3-21/12+55/15=160/60-630/60+220/60=160/60-410/60=-250/60=-25/6

3) 6/17*34/39=2/17*34/13=68/221

4) 7/8*5/4= 35/32= 1i 3/32

5) 13/2*4/13-8/15 : 2= 2/1-8/15:2=2-8/15*1/2=2-4/15=26/15

6)  6/24- 3/24+20/24= 23/24

7) 11/2-8/3+27/8=11/2-64/24+81/24=132/2464/24+81/24=149/24=6 i 5/24

8) 1/2*10/3=5/3= 1 i 2/5

9) 5/12*9/1=15/4= 3i 3/4

10) 50/7:25/14-7/5*15/28= 50/7*14/25-21/28=4-21/28=3i 7/28

11) 48/108-18/108+45/108=48/108-66/108=-18/108= -3/18

12) 17/4-21/10+21/20=85/20-42/20+21/20=85/20-63/20=22/20=1 i 1/10

13) 15/4*8/5=6

14) 3/2*7/3= 7/2=3 i 1/2

15) 8/28+15/28-10/28=23/28-10/28=13/28

16) 2/5

17) 34/8*32/35=136/35=3i 31/35
