Let B = the number of boys and G = the number of girls, then:
\n" ); document.write( "\"B%2F%28B%2BG%29+=+3%2F8\" \"The ratio of the number of boys (B) to total students (B+G) is 3:8 (\"3%2F8\").\"
\n" ); document.write( "\"G+=+10\" \"There are 10 girls.\" So...
\n" ); document.write( "\"%28B%2FB%2B10%29+=+3%2F8\" Solve for B. Cross-multiply.
\n" ); document.write( "\"8B+=+3%28B%2B10%29\" Simplify.
\n" ); document.write( "\"8B+=+3B%2B30\" Subtract 3B from both sides.
\n" ); document.write( "\"5B+=+30\" Divide both sides by 5.
\n" ); document.write( "\"highlight%28B+=+6%29\" This is the number of boys.
\n" ); document.write( "The total number of students is:
\n" ); document.write( "\"B%2BG+=+6%2B10\"=\"highlight%2816%29\"
\n" ); document.write( "
\n" ); document.write( "
