[tex]Let's\ try\ listing\ numbers \\ that\ is\ not\ more\ than\ 530\ but\ equal\ to\ it\ when\ estimated. \\ \\ 529=530 \\ 528=530 \\ 528=530 \\ 527=530 \\ 526=530 \\ \boxed{525=530} \\ 524 \neq 530 \\ 523 \neq 530 \\ 522 \neq 530 \\ 521 \neq 530 \\ \\ Thus,\boxed {525}\ is\ the\ smallest\ number\ when\ estimated\ by\ \boxed{530} \\ \\ Hope\ it\ Helps:) \\ Domini[/tex]
