81/6- 4 5/8 plz me answer this question asap it is due tomorrow

3 13/24

Step-by-step explanation:

1) 8 1/6 - 4 5/8

2) 49/6 - 37/8

3) 196/24 - 111/24

4) 85/24

5) 3 13/24

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

you first to choose the points and then move from then as the slope you have
