PLEASE HELP! Explain how performing operations in an expression with only percent's is different than performing operations in an expression that has both percents and decimals.

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.  

the best estimate is 3 because   8 can only go into 24 3 times

sorry i do not     know the answer
