Question 1148162
.
<pre>

Let x be the number of children in the park.


Then the number of adults is (374-x), according to the condition.


Further, the condition says that


    {{{(374-x)/x}}} = {{{15/7}}}.


To solve this equation, cross multiply and then simplify


    7*(374 - x) = 15x

    7*374 - 7x = 15x

    7*374      = 15x + 7x

    7*374      = 22x

    x           = {{{(7*374)/22}}} = 119.


<U>ANSWER</U>.  There are 119 children in the park.
