The denominator in the expression has 10 as a common factor,


3210+7510110


and it is therefore sufficient to multiply the top and bottom of each fraction by the other factors in the denominators in order to obtain a common denominator,


35205+725021521052=15100+1410010100


The lowest common denominator (LCD) is therefore 100 , and the expression is equal to


15100+1410010100=10015+1410=19100
