Answer:
Option D - x = 3 3/5
Step-by-step explanation:
Lets make the left side into an improper fraction : 
2 2/5 = 12/5 
Now let's make both fraction into equivalent ones but with the same denominator : 
2/3 = 10/15 
12/5 = 36/15 
Now we substitute the equivalent values back into the equation : 
10/15 × x = 36/15 
Now we multiply both sides by 15 to remove the denominators: 
10 × x = 36 
Now we divide both sides by 10 and simplify : 
x = 36/10
x = 18/5 
x = 3 3/5 
So our answer will be Option D
