You can set up a proportion to help sovle this kind of problem:
\n" ); document.write( "Let H = the number of students who rode horses to school and W = the number of students who walked to school, then you can write:
\n" ); document.write( "\"H%2FW+=+2%2F9\"
\n" ); document.write( "Now you can substitute the W with 18 since that is the number of students who walked to school:
\n" ); document.write( "\"H%2F18+=+2%2F9\" Now you can solve this for H, the number of students who rode horses to school:
\n" ); document.write( "\"H%2F18+=+2%2F9\" Multiply both sides by 18.
\n" ); document.write( "\"H+=+2%2818%29%2F9\"
\n" ); document.write( "\"H+=+4\"
\n" ); document.write( "The number of who rode horses to school was 4.\r
