A quick approach is to test a few values.
For example, 130 is 10% of 1300
Since 6.5 is less than 130, we know the correct answer must be less than 10%
Eliminate D and E
Also, 13 is 1% of 1300
Since 6.5 is less than 13, we know the correct answer must be less than 1%
Eliminate B and C
Answer: A
---------------------------------
ALTERNATE APPROACH
We want convert \(\frac{6.5}{1,300}\) to a percent.
First simplify by dividing top and bottom by 6.5 to get: \(\frac{1}{200}\)
From here we can divide numerator and denominator by 2 to get: \(\frac{0.5}{100} \)= 0.5%

It is quick to solve this problem using word translations:
6.5 is what percent of 1,300?
is -> =
what percent -> p/100
of -> multiply
6.5 = (p/100)(1,300)
Divide both sides by 1,300:
6.5/1,300 = p/100
Multiply both sides by 100:
0.005 = p/100
0.5% = p
6.5 is what percent of 1,300?
is -> =
what percent -> p/100
of -> multiply
6.5 = (p/100)(1,300)
Divide both sides by 1,300:
6.5/1,300 = p/100
Multiply both sides by 100:
0.005 = p/100
0.5% = p
