Answer 1

1. 33/7+8/3=99/21+56/21=155/21=7i 8/21

2. 21/8+19/12=63/24+38/24=4 i 6/24= 4 i 1/4

3. 127/30+23/12=254/60+115/60=369/60=6 i 9/60= 6 i 3/20

4. 47/6+11/4= 94/12+33/12=127/12=10 i 7/12

5. 63/10+43/15= 189/30+86/15=275/30=9 i 5/30= 9 i 1/6

6. 62/15- 29/20= 248/60-87/60=161/60=2 i 41/60

7. 28/9-29/12=112/36-87/36=25/36

8. 51/8-35/12= 153/24-70/24-83/24=3 i 11/24
