Rounding whole numbers needs the understanding of the decimal places. To round to the nearest decimal place means to find the closest number having all zeros to the right of the that decimal place. Our rule of rounding numbers states that when the digit 5, 6, 7, 8, or 9 appears in the lower one decimal place, round up; when the digit 0, 1, 2, 3, or 4 appears in the lower one decimal place, round down.

Some real-life situations involving numbers can directly be solved using the four fundamental operations: addition, subtraction, multiplication and division. For instance, if 1 apple cost 5 pesos, how much do 15 apples cost? To solve this problem simply multiply 15 by 5. However, there are other practical applications which can best be solved by looking for a general pattern, relationship or formula before arriving at the answers.
Naming decimal places corresponds to a place value of a certain digit in a decimal number. This is different from reading decimal numbers because it only tackles the name of a place value of a certain digit while reading decimal number tackles reading the whole decimal number.
