Question

A group of 400 town residents is asked to attend a town hall meeting. Of the 400 residents asked to attend 36 were able to attend. What percentage of the town residents were able to attend?
A. 1.1%
B. 90%
C. 11%
D. 9%

Answer 1

We have to find the percentage ratio of two numbers. It is $\frac{36}{400}*100 = 9%$. And the correct answer is D). 

Alternatively, by setting up a ratio, we can write that If
                    400_____100%
                      36_____x
And x=9%
