Question

If there are 12 girls and 15 boys in a class, which ratios are true?

Answer 1

The first three are true

Answer 2

Answer:

12 girls to 27 students

5 boys to 9 students

15 boys to 12 girls

Step-by-step explanation:

The first thing we have to know is that the total number of students is 27 .

- 12 girls to 27 students  is correct because there are 12 girls out of a total of 27 estudiantes

- 5 boys to 9 students is correct because it uses a common denominator that is 3  (boys: 15 / 3 = 5 and students: 27 /3 = 9)

- 15 boys to 12 girls is saying the same of the statement

The last one 3 girls to 5 boys does not have a common denominator for both factors so this last option is false .
