Answer: A) 51%
Explanation:
We can estimate the percentage of pass completions by rounding both values. While estimation does not give an exact answer it will give one that is close.
38 rounds up to 40 and 79 rounds up to 80.
Now it is easier to divide.
40/80=1/2
1/2=50%
The closest answer to 50% is 51% which must be the answer.
