Let x be the fractional part that is 37 (A number between 0 and 1). Then 1-x is the part that is 35
\n" ); document.write( " $\"%281-x%29%2A+35+%2B+x%2A37+=+35.453\"$
\n" ); document.write( " $\"35+-+35x+%2B+37x+=+35.453\"$
\n" ); document.write( " $\"2x+=+0.453\"$
\n" ); document.write( " $\"x+=+0.2265\"$
\n" ); document.write( "So the percentage that is 37 is 22.65%
\n" ); document.write( "Check your answer
\n" ); document.write( "Does 0.2265*37 + (1-0.2265)*35 = 35.453???\r
