As shown in the table the amount of carbon is 45 per 

 cent (45%) of the total weight. To solve this problem 

 we must find 45% of 2,000 pounds. One per cent (l'~; ) 

 of a numlier means one part in one hundred parts, which 

 is the same as saying one one-hundredth (.01) part of the 

 number. 45% is .45 of the number. To get 45%c of a 

 number we therefore multiply by .45.
