Answer 2

Answer:

So odd and even numbers from 30–50.

To count the numbers fast, lets use this:

30+50=80

32+48=80

34+46=80 and so on and the result will be 80x5 PLUS the 40 in the middle which equals 440

And the odd numbers

31+49=80

33+47=80 and so on and the result will be 80x5 which equals 400

Odd : Even = 440:400 which we can simplify up to 11:10.
