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