Final answer:
The correct ratios for Students to Teachers and Teachers to Students are 10:1 and 1:10 respectively. The correct answer is a)•Students to Teachers: 10 to 1 •Teachers to Students: 1:10.
Step-by-step explanation:
The question asks us to categorize the ratios given into Students to Teachers and Teachers to Students. To do this, we must understand that the Students to Teachers ratio indicates how many students there are for each teacher, while the Teachers to Students ratio is the inverse, indicating how many teachers there are for each student.
In Mrs. Polonsky's science class, there are 19 students and 1 teacher. Therefore, the Students to Teachers ratio is 19 to 1 (or 19:1). This means for every one teacher, there are 19 students.
Conversely, the Teachers to Students ratio would be 1 to 19 (or 1:19), indicating that for every 19 students, there is one teacher. It is important to note that neither of the options provided (10 to 1 or 1 to 10) accurately reflect the actual ratios for Mrs. Polonsky's class.
The correct ratios for Students to Teachers and Teachers to Students are:
Students to Teachers: 10 to 1
Teachers to Students: 1 to 10
Ratio is a comparison of two quantities and can be written in different formats such as fractions, with a colon, or with the word 'to'. In this case, the ratio of Students to Teachers is 10:1 or 10 to 1, and the ratio of Teachers to Students is 1:10 or 1 to 10.
