Question

round to the nearest given place.
1.17929 thousandths

Explanation:

Step1: Identify the place

The thousandths place in 1.17929 is the third decimal digit, which is 9 (1.17\(9\)29).

Step2: Check the next digit

The digit to the right of the thousandths place (ten - thousandths place) is 2. Since 2 < 5, we don't round up the thousandths place digit. But wait, wait, no - wait, the number is 1.17929. Wait, thousandths place is the third decimal: 1.17929, so the digits are: first decimal: 1 (tenths), second: 7 (hundredths), third: 9 (thousandths), fourth: 2 (ten - thousandths), fifth: 9 (hundred - thousandths). Wait, no, wait, 1.17929: let's write it as 1.1 (tenths), 1.17 (hundredths), 1.179 (thousandths), 1.1792 (ten - thousandths), 1.17929 (hundred - thousandths). Wait, no, the question is to round to the nearest thousandths. So the thousandths digit is 9, the next digit (ten - thousandths) is 2. Wait, but wait, maybe I made a mistake. Wait, 1.17929: the digits after the decimal are: position 1: 1 (tenths), position 2: 7 (hundredths), position 3: 9 (thousandths), position 4: 2 (ten - thousandths), position 5: 9 (hundred - thousandths). Wait, no, no, the decimal places: tenths (1st), hundredths (2nd), thousandths (3rd), ten - thousandths (4th), hundred - thousandths (5th). So for 1.17929, rounding to the nearest thousandths (3rd decimal place). The digit in the thousandths place is 9, the next digit (4th decimal place) is 2. Since 2 < 5, we keep the thousandths place as it is? But wait, that would be 1.179? But wait, no, wait, maybe I miscounted. Wait, 1.17929: let's write it as 1.17929. So thousandths place is the third decimal: 9. The next digit is 2 (ten - thousandths). So since 2 < 5, we don't round up the 9. But wait, that can't be. Wait, no, wait, maybe I messed up the digits. Wait, 1.17929: 1 (units), 1 (tenths), 7 (hundredths), 9 (thousandths), 2 (ten - thousandths), 9 (hundred - thousandths). So when rounding to the nearest thousandths, we look at the ten - thousandths place (digit 2). Since 2 < 5, we round down, so the number remains 1.179? But wait, no, wait, maybe I made a mistake. Wait, no, the ten - thousandths digit is 2, which is less than 5, so we don't increase the thousandths digit. But wait, the thousandths digit is 9, and we don't round up, so the number rounded to the nearest thousandths is 1.179? Wait, but that seems wrong. Wait, no, wait, let's check again. Wait, 1.17929: the thousandths place is 9, the next digit is 2. So 2 is less than 5, so we keep the thousandths place as 9, so the number is 1.179. But wait, wait, maybe I misread the number. Let me check again: 1.17929. Yes, so thousandths place is 9, next digit is 2. So we don't round up. So the rounded number is 1.179? Wait, no, wait, no, wait a second. Wait, the number is 1.17929. Let's expand it: 1 + 0.1 + 0.07 + 0.009 + 0.0002 + 0.00009. So when rounding to the nearest thousandth, we look at the digit after the thousandth place, which is 0.0002 (the 2 in the ten - thousandths place). Since 2 < 5, we round down, so we keep the thousandth place as 9, so the number is 1.179. But wait, that seems correct. Wait, but maybe I made a mistake in the place value. Let's confirm:

- Tenths: 1 (0.1)
- Hundredths: 7 (0.07)
- Thousandths: 9 (0.009)
- Ten - thousandths: 2 (0.0002)
- Hundred - thousandths: 9 (0.00009)

So to round to the nearest thousandth, we look at the ten - thousandths digit (2). Since 2 < 5, we don't round up the thousandths digit. So the number rounded to the nearest thousandth is 1.179. Wait, but wait, no, wait, the original number is 1.17929. Wait, maybe I made a mistake. Wait, no, the rule is: when rounding to a certain decimal place, look at the next digit. If it's 5 or more, round up; if less than 5, round down. So thousandths place is 9, next digit (ten - thousandths) is 2. 2 < 5, so we leave the thousandths place as 9. So the rounded number is 1.179.

Wait, but wait, let's check with another approach. Let's consider the number 1.17929. The thousandths place is the third decimal. So we can write the number as 1.179 + 0.00029. So when rounding to the nearest thousandth, we see if 0.00029 is closer to 0 or to 0.001. Since 0.00029 < 0.0005, it's closer to 0, so we keep the thousandths place as 9, so the number is 1.179.

Answer:

1.179
