Well, you can turn these into percents to get a different view if the fraction thing is messing you up. Do this by dividing the top by the bottom and multiplying bu 100.
1/8 = 0.125 0.125 x 100 = 12.5%
3/8 = 0.375 0.375 x 100 = 37.5%
1/4 = 0.25 0.25 x 100 = 25%
1/8 is the smallest and 3/8 is the largest
Another way to do this would be to multiply 1/4 so all three numbers have equal denominatior.
1/4 x 2/2 = 2/8
comparing, 2/8 3/8 and 1/8, you can see that 1/8 is the least and 3/8 is the most
Mccain's essay was very exaggerating to me and managed to extend my concept of patriotism, thus leaving the concept more complete and efficient. Before reading the essay, I believed that patriotism is related exclusively to the feeling of love for the country, within that feeling it was not correct to criticize and not support certain elements, but just to love the country unconditionally. MacCain's essay showed me that criticism of the country is part of patriotism, because it is through criticism that we recognize the defects that our society has and that need to be changed. This is able to motivate us to fight for a better country. Striving for improvement represents love for the country and that represents patrotism.
Answer:
C. The scientist's conclusion is flawed because the number of hours of sunlight changed and, therefore, the experiment is not controlled.
Explanation:
A controlled experiment is an experiment used to test a single variable at a time. The variable that is being tested is called the independent variable, and it is directly manipulated by a scientist. The rest of the variables need to remain unchanged in order not to get wrong results like the scientist in the given scenario.
As the scientist is trying to see how gamma rays affect marigolds, only the gamma ray exposure is supposed to change throughout the experiment. The amount of water remained the same, but the number of hours of sunlight didn't. That's why we don't know what exactly affected the growth of marigolds - the sunlight or the gamma rays? And that's why the scientist's conclusion is flawed.
