Final answer:
To find the total number of students at the high school, we use the given that 262 students represent two-sevenths of the total. By setting up a proportion and solving for the total, we calculate that there are 917 students at the high school.
Step-by-step explanation:
The question asks us to find the total number of students at a high school given that 262 students represent two-sevenths of the total. To find the total, we set up a proportion: 262 = 2/7 of Total. Multiplying both sides of the equation by 7/2 (the reciprocal of 2/7) will give us the total number of students. Therefore, the calculation will be 262 * (7/2) = 917, which means there are 917 students at the high school in total.
