Make Sure you distribute first, then go from there
There would be 10 mens out of the 20 because since 5 is a half of 10 then u could predict that there is a half of people that are mens in the 20 people.
From 3.00 to 3.60 is
60% change
To solve you multiply everything by 100
300 to 360 you see that the change is 60
so it is a 60% change
Hope this helps :)
