Answer:

81 girls are in the class

Step-by-step explanation:

in these kinds of questions to find the amount of girls in the class we need to first divide the given number; which in this case is 27, with the starting number; which is 3, and we get 9.  Using the 9 we got from the earlier equation we will multiply the 9 by the number of girls in the class, which is also 9 and we get 81 as our answer.
