Hundreds, Tens, Ones

The expanded form of a number is a way of writing the number as the sum of the values of its digits. For example, the expanded form of 496 is 400 + 90 + 6.

To identify the hundreds, tens, and ones in a number, look at the place value of each digit. The leftmost digit represents hundreds, the middle digit represents tens, and the rightmost digit represents ones.

The expanded form of 112 is 100 + 10 + 2.

The expanded form of 855 is 800 + 50 + 5.

In the number 529, the digit 5 is in the hundreds place, so its value is 500.

Place value refers to the value of a digit based on its position in a number. For example, in the number 3,049, the digit 3 is in the thousands place, giving it a value of 3,000.

The expanded form of 3,049 is 3,000 + 0 + 40 + 9.

The expanded form of 400 is 400 + 0 + 0.

To convert a number into its word form, you write out the value of each digit according to its place value. For example, 529 is written as 'five hundred twenty-nine'.

In the number 112, the digit 2 is in the ones place, so its value is 2.
