525525/252525×525252/252252
=21021*25/10101*25×131313*4/63063*4
=21021/10101×131313/21021*3
=131313/10101*3
=13*10101/10101*3
=13/3
=21021*25/10101*25×131313*4/63063*4
=21021/10101×131313/21021*3
=131313/10101*3
=13*10101/10101*3
=13/3

525525/252525×525252/2522
=(525525x525252)/(252525x252252)[分子和分母同时除以10101]
=（525525X52）/（25X252252）[分子和分母同时除以25]
=（21021X52）/252252[分子和分母同时除以21021]
=52/12
=13/3
=(525525x525252)/(252525x252252)[分子和分母同时除以10101]
=（525525X52）/（25X252252）[分子和分母同时除以25]
=（21021X52）/252252[分子和分母同时除以21021]
=52/12
=13/3
