One standard size for the United States flag is 19 feet by 10 feet.

What is the ratio of length to width for this flag?

19 : 10 = 19 : 10

Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 19 and 10 is 1

Divide both terms by the GCF, 1:

19 ÷ 1 = 19

10 ÷ 1 = 10

The ratio 19 : 10 cannot be reduced further by dividing both terms by the GCF = 1 :

This ratio is already in lowest terms.

Therefore:

19 : 10 = 19 : 10

Step-by-step explanation:

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.
