what is 2.4 rounded to the nearest tenth
The correct answer and explanation is:
Correct Answer: 2.4
Explanation (300 words):
Rounding a number to the nearest tenth means adjusting it to one digit after the decimal point. Let’s walk through how to round 2.4 to the nearest tenth step by step:
- Understand the Place Values:
In the number 2.4, the digit 2 is in the ones place, and the digit 4 is in the tenths place. There are no digits after the tenths place (hundredths, thousandths, etc.). - Check the Digit After the Tenth Place:
To round to the nearest tenth, we look at the hundredths place, which is the digit two places after the decimal.
In 2.4, there is no hundredths digit, which means it’s treated as a 0. - Apply Rounding Rules:
The rounding rule is:- If the digit in the hundredths place is 5 or more, round the tenths digit up by 1.
- If it is less than 5, leave the tenths digit as it is.
- Final Result:
The tenths digit stays the same, and no other digit is added or changed.
So, 2.4 rounded to the nearest tenth is 2.4.
Extra Tip:
If the number were 2.46, you’d look at the hundredths place (6), and since 6 is greater than 5, you’d round up to 2.5.
But with 2.4, no rounding is needed—it’s already at the nearest tenth. This makes 2.4 both the original number and the rounded result.
