Praxis 5511 Practice Test Practice Question
In a group of 160 students, 60 are seniors. What is the ratio of the number of seniors to the number of non-seniors?
Correct Answer: B
Rationale: To find the ratio of seniors to non-seniors, first determine the number of non-seniors. With 160 students total and 60 seniors, the number of non-seniors is 160 - 60 = 100. The ratio of seniors to non-seniors is then 60 to 100. Simplifying this ratio by dividing both numbers by 20 gives 3 to 5.
Option A (3 to 4) miscalculates the non-seniors, suggesting fewer than there are. Option C (3 to 8) incorrectly simplifies the ratio, failing to account for the total number of non-seniors. Option D (3 to 11) also misrepresents the relationship between seniors and non-seniors, leading to an inaccurate ratio.
