Question

round 1.9255 to the nearest tenth.

Explanation:

Step1: Identify the tenths place

The number is \(1.9255\). The tenths place is the first digit after the decimal, which is \(9\). The next digit (hundredths place) is \(2\).

Step2: Apply rounding rule

To round to the nearest tenth, we look at the hundredths digit. If the hundredths digit is less than \(5\), we keep the tenths digit the same; if it's \(5\) or more, we round up the tenths digit. Here, the hundredths digit is \(2\), which is less than \(5\). But wait, wait, no—wait, \(1.9255\): tenths place is \(9\), hundredths is \(2\). Wait, but wait, maybe I made a mistake. Wait, no, let's check again. Wait, \(1.9255\): the tenths digit is \(9\), the digit to the right (hundredths) is \(2\), which is less than \(5\), so we keep the tenths digit as is? But wait, no, wait, \(1.9255\) rounded to the nearest tenth: the tenths place is \(9\), the next digit is \(2\), so we don't round up. But wait, that would be \(1.9\)? Wait, no, wait, maybe I messed up. Wait, no, let's recall the rounding rule: look at the digit in the hundredths place (the digit to the right of the tenths place) to decide if we round the tenths place up or not. The number is \(1.9255\), so tenths: \(9\), hundredths: \(2\). Since \(2 < 5\), we round down, so the tenths place remains \(9\), and the digits after tenths are dropped. So \(1.9255\) rounded to the nearest tenth is \(1.9\)? Wait, no, wait, that can't be right. Wait, no, wait, \(1.9255\): let's write it as \(1.9\) (tenths place) and the next digit is \(2\) (hundredths). So when rounding to the nearest tenth, we look at the hundredths digit. If it's less than \(5\), we keep the tenths digit. So \(1.9255\) rounded to the nearest tenth is \(1.9\)? Wait, but wait, maybe I made a mistake. Wait, no, let's check with another approach. The tenths place is \(9\), the number is \(1.9255\). The interval between \(1.9\) and \(2.0\) is being considered. The midpoint is \(1.95\). Since \(1.9255 < 1.95\), it's closer to \(1.9\)? Wait, no, \(1.9255\) is \(1.9 + 0.0255\), so it's closer to \(1.9\) than to \(2.0\) because \(0.0255 < 0.05\) (the distance from \(1.9\) to \(2.0\) is \(0.1\), half of that is \(0.05\); since \(0.0255 < 0.05\), it's closer to \(1.9\)). Wait, but wait, maybe I messed up the digits. Wait, \(1.9255\): the tenths digit is \(9\), hundredths is \(2\), so yes, we don't round up the tenths digit. So the rounded number is \(1.9\)? Wait, but that seems counterintuitive because \(9\) is a high digit, but the next digit is \(2\), which is less than \(5\). So yes, the rule is: look at the digit to the right of the place you're rounding to. So tenths place: look at hundredths. Hundredths is \(2\), so round down. So \(1.9255\) rounded to the nearest tenth is \(1.9\).

Answer:

\(1.9\)
