"Write the place and the value of the underlined digit" is a math instruction that requires identifying the position of a specific digit within a number and determining its value based on that position. The "place" refers to the position of the digit within the number, such as ones, tens, hundreds, etc. The "value" is the numerical worth of that digit based on its place within the number. This task helps students understand the concept of place value and how digits contribute to the overall value of a number.
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. If it does not contain a fractional part then the decimal representation does not require a decimal point. The name is derived from "deci" which means pertaining to ten.
a digit is any number from 0 to 9
