Agroup 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%

We have to find the percentage ratio of two numbers. It is . And the correct answer is D). 

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

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
