Julie reads 1/3 of a book on Tuesday and 1/4 of the book on Wednesday. How much of the book does she have left to read?

5/12

Step-by-step explanation:

The whole book can be represented as 12/12 because 12 divided by 12 equals one whole ( or one). 1/3 * 4/4(one rewritten) = 4/12 We then need to add this to 1/4 * 3/3 (one rewritten again) = 3/12

4/12 + 3/12 == 7/12

7/12 is the amount Julie did read so we subtract this from 12/12 to get the

5/12

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.
