Question

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?

Answer 1

1/4 of the total girls = 16
1/4x = 16
x = 16 * 4
x = 64 girls

1/8 of the total boys = 7
1/8x = 7
x = 7 * 8
x = 56 boys

for a total of (64 + 56) = 120 students <===
