there are 30 students in a class, including 16 boys. write each
ratio.
@ girls to boys ® boys to girls
(e) girls to all students ( boys to all students girls to boys

14 girls : 16 boys, 16 boys : 14 girls, 14 girls : all 30 students, 16 boys : all 30 students.

Step-by-step explanation:

I solved this because we are told that there are 16 boys so 30-16=14 so then we have 14 girls. To wright our awnsers we then look at how the question is worded. If it say boys to girls then its going to be 16 : 14, or if it says boys to all students it will be 16 : 30. I hope that you understand this and best of luck.

30 Girls and Boys

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
