we are told that 4 out of 10 students are taking a trip. To determine how many students will be taking a trip from a 150 students class we can use a simple rule of three, that is:
[tex]\begin{gathered} 4\text{ trip}\rightarrow10\text{ students} \\ x\rightarrow150\text{ students} \end{gathered}[/tex]Cross multiplying we get:
[tex]x=150\text{ students(}\frac{4trip}{10\text{ students}})[/tex]solving the operations:
[tex]x=60\text{ trip}[/tex]Therefore, 60 students are taking a trip.
