The ratio of the numerator to the denominator of a fraction is 2 to 3. If both the numerator and the denominator are increased by 2, the fraction becomes . What is the original fraction?

a) If both the numerator and the denominator are increased by 2, the fraction becomes?

= 4/5

b) What is the original fraction?

= 2/3

Step-by-step explanation:

The ratio of the numerator to the denominator of a fraction is 2 to 3.

a) If both the numerator and the denominator are increased by 2, the fraction becomes .

2:3 = 2/3

We are told that both numerator and denominator are increased by 2, hence:

2 + 2/3 + 2

= 4/5

b) What is the original fraction?

The ratio of the numerator to the denominator of a fraction is 2 to 3.

Hence, the original fraction is:

2:3 = 2/3

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.
