Concept: Find the number of digits after the decimal point for each number. Use the fact that the number of decimal places is the same as after the decimal point. Therefore, find the same number of decimal places  in the specified list of numbers.
The number of decimal places with the same number of decimal places is called the same number of decimal places. In other words, a decimal number with the same number of digits after the decimal point is said to be similar to a decimal number. Decimal numbers that are not equal are called odd decimal numbers. In other words, decimal numbers that do not have the same number of digits after the decimal point are called odd decimal numbers.
For Question Image ,  the number of digits to the right of the decimal point is 1.
