If Levi eats 1/5 of pie, Travis eats 1/4 of the same pie, and Delaney eats 2/7 of the same pie, what fraction of the pie did they eat altogether

ANSWER

Since the word altogether which is the key word means the sum so we will add all the fractions i.e

= 1/5 + 1/4 + 2/7

LCM of 5,4 and 7 = 140

= ⅕×140 + ¼×140 + ²/⁷×140

140

= 28 + 35 + 40

140

= 103

140

Therefore the total fraction is 103

140

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.  

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
