One-fourth of the girls and one-eighth of the boys in a class retake their school pictures. The photographer retakes pictures for 16 girls and 7 boys. How many students are in the class?
120
(1/4)g = 16 ---> g = 64
(1/8)b = 7 ---> b = 56

That is Right
To find the total number of students in the class, we need to determine the number of girls and boys who retake their school pictures, and then calculate the fractions of each gender in the class.
Let's start by finding the number of girls who retake their pictures. We are given that one-fourth of the girls (1/4) retake their pictures, which corresponds to 16 girls. To find the total number of girls in the class, we can multiply 16 by the reciprocal of 1/4, which is 4/1:
16 * (4/1) = 64 girls
Now, let's determine the number of boys who retake their pictures. We are told that one-eighth of the boys (1/8) retake their pictures, which corresponds to 7 boys. Similar to before, we can find the total number of boys in the class by multiplying 7 by the reciprocal of 1/8, which is 8/1:
7 * (8/1) = 56 boys
Finally, to find the total number of students in the class, we add together the number of girls and boys:
64 girls + 56 boys = 120 students
Therefore, there are 120 students in the class.
