(a Rational number is a number that can be written as a ratio of two integers)

Step-by-step explanation:

By definition a Rational number is that number that can be expressed as a fraction:

Where the numerator "a"  is an integer and the denominator "b" ()

Then, in other words, a Rational number is a number that can be written as a ratio of two integers.

Since the denominator "b" can be , we know that every Integer is a Rational number.

Below are some examples of Rational numbers:

well first make sure that you are black. then rob a gas station and the kill the attendant

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.
