Human: In Mr. Bolton's class of 25 students, 2/5 of the students like maths, 1/3 of the remaining students like science, and the rest of the students like history. Calculate the combined total number of students who like history and those who like maths. Assistant:
If there are 25 students in the class, then 2/5*25 = 10 students like maths.
The number of students who don't like math is 25-10 = 15 students.
If 1/3 of the students that don't like math like science, then 1/3*15 = 5 students like science.
The remaining number of students who enjoy history is 15-5 =10
The combined total for the students who want history and maths is 10+10 = 20
