Answer:
Start: Brown feather % is 97% Grey feather % is 3%
End: Brown feather % is 19% Grey feather % is 81%
Step-by-step explanation:
Start:
There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7
divide each number by 7(679/7 and 21/7)
and you get 97 and 3 which will be your percentages
End:
There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4
divide each number by 7.7(140/7.4 and 600/7.4)
and you get about 19(rounded) and about 81(rounded) which will be your percentages
