Justin and Desiree each wrote a ratio comparing the numbers of students and tables in their classroom. There are 6 tables in the room with 4 students at each table. Justin states that the ratio is 4:1. Desiree insists the ratio is 24:6. They both ask Luke to tell them which ratio is correct. Which statement below would be the best answer for Luke?

• Justin is correct because there are 4 students per table. A ratio is not correct unless it uses the smallest possible numbers.

• Desiree is correct because there are 24 students to 6 tables in the room. A ratio must account for the total number of each value.

• Both are correct. Desiree’s ratio compares the total number of students in the room to the total number of tables, while Justin’s is equivalent but simplified to students per table.

• Neither is correct because they should have 4:6 or 2:3 for the 4 students and 6 tables.
