Question

There are 75 students 3/5 of the class are science majors. How many students are not, can you write out the answer so I can see how to solve problem

Answer 1

Step 1

Given;

`\begin{gathered} \text{Total number of students = 75} \\ (3)/(5)of\text{ the total = Science major students} \end{gathered}`

Required; To find how many students are not science majors

Step 2

Find the number of science major students

`(3)/(5)*75=45\text{ science major students}`

Step 3

Find the number of students who are not science majors

`\begin{gathered} \text{Total number of students = science majors + non-science majors} \\ 75=45\text{ + non-science majors} \\ \text{non}-\text{science majors=75-45=30 non-science major students} \end{gathered}`

Hence, there are 30 students who did not major in science.
