Which equation determines the proportion of ground squirrels alive at the start of year 1-2?

Hi! If you took the same test as me, the answer should be "64/80 = 0.800"

But, you might have a different graph.

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.

so, converting firstly the mixed fractions to improper fractions and then "adding".
