You can put this solution on YOUR website!
Let x be the fractional part that is 37 (A number between 0 and 1). Then 1-x is the part that is 35
%281-x%29%2A+35+%2B+x%2A37+=+35.453
35+-+35x+%2B+37x+=+35.453
2x+=+0.453
x+=+0.2265
So the percentage that is 37 is 22.65%
Check your answer
Does 0.2265*37 + (1-0.2265)*35 = 35.453???
