The answer would be 1.6 because 2 - 4/5 is 1.2, and then 1.2 x 1/2 is 1.6
Answer:

Step-by-step explanation:
Given


Required
Compare both ratios


Multiply ratio 2 by 4


This gives:


Write both ratios as fractions


Get decimal equivalent:


Comparing both, we have that


Conclusively;

There were 4 number of treatment conditions compared in this experiment for the given degree of freedom.
We have,
df = 3, 36
Now,
We know that,
Degree of freedom (df) = Number of treatments (t) - 1
i.e.
df = t - 1
So,
We have,
df = 3
Now,
Substituting the values,
We get,
3 = t - 1,
i.e.
t = 4
So, number of treatments conditions = 4
Hence we can say that there were 4 number of treatment conditions compared in this experiment for the given degree of freedom.

9/8 + 9/4 = 27/8.
Multiply 9/4 by 2.
9/4 • 2 = 18/8
Then, add the fractions.
9/8 + 18/8 = 27/8
Simplify 27/8.
27/8 = 3 3/8
