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

12 girls to 27 students
5 boys to 9 students
15 boys to 12 girls
3 girls to 5 boys

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 .

853.3

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
