Place value refers to the value of a digit based on its position within a number. Each digit in a number has a specific place value, which is determined by its position relative to the decimal point. For example, in the number 245, the place value of the digit 2 is 200, the place value of the digit 4 is 40, and the place value of the digit 5 is 5.
In the number 45783, the value of the digit 3 is determined by its position in the number. It is in the units place, which means its value is simply 3. Therefore, the value of the 3 in 45783 is 3.
No, a 4-digit number is not always less than a 5-digit number. The value of a number is determined by the digits it contains, not the number of digits. For example, the 4-digit number 9999 is greater than the 5-digit number 1000. It is important to consider the actual numerical value when comparing numbers, not just the number of digits.
In the number 4795, the digit 7 is in the hundreds place. This means that the place value of 7 is 700. The place value of a digit is determined by its position in the number, with each place representing a power of 10 (ones, tens, hundreds, etc.).
In the number 15386, the 1 is in the thousands place. Therefore, its value is 1,000. The value of a digit in a number is determined by its place in the number, with each place representing a power of 10.
