Write the pair of fractions as a pair of fractions with a common denominator

I'll do the first two problems to get you started

Problem 1

1/2 = 3/6

1/3 = 2/6

For the first fraction, I multiplied top and bottom by 3. Note how 3 is the denominator of the second fraction.

For the second fraction, I multiplied top and bottom by 2. Note how 2 is the denominator of the first fraction.

Problem 2

1/2 = 5/10

3/5 = 6/10

Like with problem 1, I multiplied top and bottom of the first fraction by the value 5 which is the denominator of the second fraction. Likewise, I did the same for the second fraction using the first denominator. The steps are essentially the same, but the numbers are different.

Problem 3 will be handled the same way. I'll let you try it out.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
