Okay so let’s start by figuring what the total number of people is. To get that we add 24 and 30. 24+30= 54 So we have a total of 54 people. Now, how many children are there? 30 children... which means the ratio is 30:54
Thirty children to fifty four people total at the museum.
Hope this helps! Contact me if you have any more questions or concerns.
