Answer:

Step-by-step explanation:
Start by multiplying both sides by 2, this will get rid of the fraction on the left side and will result in the equation 
Then, subtract 2m from both sides, which leaves the equation as 
Then, subtract 6 from both sides, this results with the equation 
Finally, divide both sides by 10, this will result in m=-1
 
        
             
        
        
        
Answer:
3:2
Step-by-step explanation:
I am assuming this means convert to whole numbers
3/5:2/5 is 6/10:4/10
6/10:4/10 is 0.6:0.4
0.6:0.4 is 6:4
6:4 is 3:2
