The student to teacher ratio at a high school is 10: 2. if the total number of students and teachers is 60: how many of them must be students? explain

50 students : 10 teachers

Step-by-step explanation:

Take 10:2 and multiply each number by another number (to get the unsimplified answer). This would turn it into 10x:2x. Then you add the two terms together to get 12x = 60. Divide both sides by 12 to get the x by itself, and you'll get x = 5. Now, if you go back to the original 10x:2x equation and substitute x for 5 [10(5):2(5)], you'll get 50:10, which is 50 students to 10 teachers.
