Explain why estimating before you divide helps you place the first digit in the quotient?
You can use estimation and place value to help you figure out where to place the first digit.
When would you use place value in real life?
You use place value for all decimal numbers that contain fractional parts. You also use place value for all decimal integers other than those containing only one-digit.
How does the position of a number determine its value?
The value of a digit in a number is the face value of the digit multiplied by its place value. In the decimal system, the value of the digit immediately to the left of the decimal point is units so that its numeric value is the face value of that digit. The place value of any other digits is ten times the place value of the digit to its right - or one tenth of the digit to its left.In the binary system, the place value goes up in multiples of 2, in the octal system in powers of 8 and in hexadecimal in 16s. There are also number systems based on other bases.
Why do you use decimal for?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point.
