Answer:

7= 2 4/5         8=2/21           9= 6 3/7          10= 1/6            11= 7/5           12=77/90

Step-by-step explanation:

3 1/5= 16/5-2/5=14/5 which equals to the same thing to 2 4/5

5/3= 35/21

11/7= 33/21

35/21-33/21= 2/21

3 3/4=15/4 times 12/7 straight ahead which is 180/28 equals to the same thing as 45/7 = 6 3/7

1/5 times 7/1 so u flip it over as u can see which is 7/5

2 1/5= 11/5    2 4/7= 18/7       11/5 times 7/18=77/90
