The sum of a negative number, 1/4 of the negative number, and 7/16 of the negative number is -13 1/2.
\n" ); document.write( ":
\n" ); document.write( "let x = the number (which will turn out to be negative)
\n" ); document.write( "Change -13 $\"1%2F2\"$ to improper fraction $\"-27%2F2\"$
\n" ); document.write( ":
\n" ); document.write( "x + $\"1%2F4\"$ x + $\"7%2F16\"$ x = $\"-27%2F2\"$
\n" ); document.write( "multiply equation by 16, cancel the denominators
\n" ); document.write( "16x + 4(x) + 7(x) = 8(-27)
\n" ); document.write( "27x = -216
\n" ); document.write( "x = -216/27
\n" ); document.write( "x = -8
\n" ); document.write( ":
\n" ); document.write( " What is the negative number? -8 \n" ); document.write( "
