Simplifying numbers involves reducing their complexity. The simplest way to do this with 4972 is to divide it by 100 to get 4.75, then multiply the result by 100 to get 475, or write it as IVII. This can be done because there are no leading zeros for thousands' place values and therefore no problem dividing by 1000. Simplification is also easy for 72 because it is a whole number. So simply divide it by 7 to get 10.43, then multiply by 70 to get 443 or write it as VIIII. This can be done because there are no leading zeros for millions' place values and therefore no problem dividing by million. Finally, combine these two simplifications to get 3776. This answer was verified using several online calculators.
