Pay attention to exactly what the question is asking for -- the number of students who turned in their forms.

The number of students has to be a whole number; 30/35 is not a valid answer.

I will explain you how to answer the first question.


The problem says about "every 7 students".


According to the condition, you can divide the entire body of 35 students in 5 group, each comprising of 7 students,

in a way that 6 out of 7 students in each group turn in their field trip form.



It means that the number of students turned in their trip form is 6 multiplied by the number of groups, which is 5.


So, the ANSWER to this question is  6*5 = 30  students.
