Select two ratlos that are equivalent to 27 : 9.
Choose 2 answers

A 3:1
B 9:3
C 6:3
D 9:6
E 12:3

Explanation:

Note how 27 and 9 have a common factor of 3.

Divide each part by this common factor

27/3 = 9

9/3 = 3

So 27:9 is equivalent to 9:3

Choice B is one of the answers

Another common factor of 27 and 9 is 9. This is the greatest common factor (GCF). Divide both parts by the GCF

27/9 = 3

9/9 = 1

The ratio 27:9 is equivalent to 3:1

Choice A is one of the answers

Another way to see why choice A and choice B are the answers is to divide the two parts of the original ratio from left to right

27/9 = 3

Then for choice A's ratio of 3:1, we do the same to get 3/1 = 3

and choice B as well to get 9/3 = 3

Each time we divide the parts of teh ratio from left to right, we end up with 3 as a result.

Something like choice C doesn't work because 6/3 = 2 and choice D is 9/6 = 1.5 and choice E is 12/3 = 4, showing all different results from 3.

answer: the answer is 127 degrees

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
