Explanation:
To find a percentage, it's the portion divided by the total. 100% represents the total between the children or adults respectively in the maintee and evening.
So, to answer, let's find the total of children and adults.
34+27 = 61 is the total for children.
38+46 = 84 is the total for adults.
Now, to find each percentage, take one of the numbers (Children-Maintee, Children-Evening) and divide it by the total we found.
34/61 = 0.557 or 55.7%
27/61 = 0.442 or 44.2%
I'm leaving it in fractional form in case you need a specific decimal answer.
As for adults, it's the same procedure.
38/84 = 0.452 or 45.2%
46/84 = 0.548 or 54.8%
