My question is: A class composed of 12 girls and 10 boys was sent to the library for their reading class. Their teacher found out that only 5/6 of the girls and 4/5 of the boys are reading. How many students are not reading? Your thoughts:

There are 12 x 5 / 6 = 10 girls who are reading. So, 12 - 10 = 2 girls are not reading. There are 10 x 4 / 5 = 8 boys who are reading. So, 10 - 8 = 2 boys are not reading. Thus, there are a total of 2 girls + 2 boys = 4 students who are not reading. The final answer: 4.
