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

3210+7510−110,

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+72502−1521052=15100+14100−10100.

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

15100+14100−10100=10015+14−10=19100.
