A bag had 100 mangoes. 2/5 are rotten and 1/3 are green. How many mangoes are ripe?

Rewrite the fractions to have a common denominator

2/5 = 6/15

1/3 = 5/15

Add together: 6/15 + 5/15 = 11/15

Subtract from 1:

1-11/15 = 4/15

4/15 of them are ripe

answer: yes youre right.

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.
