In Harold’s class, there are 7 boys for every 6 girls. Identify three equivalent ratios to compare boys to girls.

The ratio of 6 /7 represent the number of boys to the number of girls in one classroom. You are given a total number of boys and girls.  

So, your ratio has to represent how many boys to the total number of boys and girls in one classroom, or 13.

The proportion becomes, 6 / 13 = x / 78.

Cross multiply getting, 13 * x = 6 * 78

Divide by 13 to solve for x, or x = 36.

There are 36 boys in all of the classrooms and 42 girls in all of the classrooms.

The ratio of boys to girls in all of the classrooms is 36 / 42, or 6 / 7.

i think the answer is fried chicken ; >

step-by-step explanation:

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 !
