Answer:
3, 5, 7
Step-by-step explanation:
Let the first of the three positive consecutive odd numbers be
.
Now, the second odd number = 
And, the third odd number = 
As per question statement, the multiplication of the first and third odd number is 9 lesser than the 6 times the second integer.
Writing the equation, we get:

As, we got a quadratic equation, so we have two solutions here.
One is positive integer and other one is negative.
So, solution is 
First number is 3.
Second number is 3 + 2 = 5
Third number is 5 + 2 = 7
25+ 45= 70
70% of 180 is 126
170-126=54
Hope that’s right! I don’t know if that’s the appropriate way to do it, but that’s how I would do it.
Ok 30min:120 min
= divided both by 30
~ gives you 1:4
