Identify place value periods

We group digits into periods: millions, thousands, and ones.

Convert number 1 to words

For \(657,004,200\):

• Millions period: \(657\) is six hundred fifty-seven.
• Thousands period: \(004\) is four.
• Ones period: \(200\) is two hundred.

Convert number 2 to words

For \(3,809,044\):

• Millions period: \(3\) is three.
• Thousands period: \(809\) is eight hundred nine.
• Ones period: \(044\) is forty-four.

Convert word 3 to standard form

"twelve million, one thousand, fifteen":

• Millions: \(12\)
• Thousands: \(001\) (must have three digits)
• Ones: \(015\) (must have three digits)
• Result: \(12,001,015\)

Convert word 4 to standard form

"eight hundred seven million, two hundred sixty thousand, seven hundred three":

• Millions: \(807\)
