\n" );
document.write( "With T being 30% of children, and since 90% represents 225, then we can use the following proportion: .9/.3 = 225/T
\n" );
document.write( "Note that this proportion is “saying”: If 90% represents the number 225, then what number represents 30%?\r
\n" );
document.write( "\n" );
document.write( "Solving , we get:

document.write( ".9T = .3(225) ------ Cross-multiplying

document.write( "T, or number of children representing 30% of enrollees = , or , or
