Round 3.619 to the nearest tenth – Rounding numbers to the nearest tenth is a fundamental mathematical skill with wide-ranging applications. Rounding 3.619 to the nearest tenth is a straightforward process that involves understanding the concept of rounding and applying specific rules. This guide provides a thorough explanation of rounding to the nearest tenth, including the steps involved, rounding rules, and practical applications.
Rounding to the Nearest Tenth
Rounding to the nearest tenth involves approximating a number to the nearest value that is a multiple of 0.1. It is a common mathematical operation used to simplify calculations and make numbers easier to read and understand.
Rounding Rules
- If the digit in the hundredths place is 5 or greater, round up the number to the next tenth.
- If the digit in the hundredths place is less than 5, round down the number to the previous tenth.
When the digit in the hundredths place is 5, it is called a “tie”. In this case, the number is rounded up if the digit in the thousandths place is odd, and rounded down if the digit in the thousandths place is even.
