Explain a method you would use to match the standard form of a number to either its word form or expanded form

Word form you would just say the number and the places like 528,000 would be five hundred twenty-eight thousand

expanded would be 500,000+20,000+8,000+000+00+0 for 528,000 you put the number and then the 0s behind it like 326 would be 300+20+6
