How many adults are at the exhibit?

It gives

    x = 15/0.12 = 125.


Then the number of adults was  125 - 15 = 110.    ANSWER

Since 15 children represent 12% of the people at the exhibit, then number of adults represent 100% - 12% (1 - .12) = 88%, or .88
With A being the number of adults, we then get the following PROPORTION: 
                                                                        .12A = 15(.88) ----- Cross-multiplying
Number of adults, or
