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.
How many students like maths? ** If there are 25 students in the class, then 2/5*25 = <<2/5*25=10>>10 students like maths.
How many students don ** The number of students who don't like math is 25-10 = <<25-10=15>>15 students.
How many students like science? ** If 1/3 of the students that don't like math like science, then 1/3*15 = <<1/3*15=5>>5 students like science.
How many students like history? ** The remaining number of students who enjoy history is 15-5 =<<15-5=10>>10
How many students like history and maths? ** The combined total for the students who want history and maths is 10+10 = <<10+10=20>>20
