Darryl has written 60 percent, or 12 pages, of his history report. Darryl wants to figure out how many pages he needs to write. Darryl's work is shown below.
part 60
Step 1: Write 60 percent as a ratio whole - 100
Step 2: Write an equivalent ratio using the number of pages done so far.
60
100
12
?
Step 3. Rewrite as: 12(100)-60
Step 4: 120-60-2
What mistake did Darryl make?
100
In Step 1. Darryl should have written the ratio as 60
In Step 2 Darryl should have put 12 in the denominator

This question isnt making too much sense to me :/

Step-by-step explanation:

answer: 2/4

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.
