Find the precision for each measurement. 120 meters, 7 1/4 inches, 30.0 millimeters
Why did the ruler go on a diet?
Because it wanted to measure accuracy with precision! 📏💪
Now, let's calculate the precision for each measurement:
1. For 120 meters, since it is given as a whole number, we assume it has no decimal places. Therefore, the precision is 0 decimal places.
2. For 7 1/4 inches, we have a fraction after the whole number. Converting it to a decimal, we get 7.25 inches. Here, the precision is 2 decimal places.
3. For 30.0 millimeters, we have a decimal number with a trailing zero. This indicates that the measurement is precise to the nearest tenth of a millimeter. Thus, the precision is 1 decimal place.
Remember, precision is all about those little details! 🧐🔍
To find the precision for each measurement, we need to determine the smallest incremental value that can be measured or represented by the given unit.
1. 120 meters: Since meters are a base unit of length, there is no fractional component to consider for precision. Therefore, the precision for this measurement is 1 meter, since it is the smallest possible unit that can be measured.
2. 7 1/4 inches: In this case, the fractional inches component (1/4 inch) represents the smallest incremental value. Therefore, the precision for this measurement is 1/4 inch.
3. 30.0 millimeters: Since this measurement includes the decimal portion of "0.0," we can assume that it was measured to the nearest tenth of a millimeter. Hence, the precision for this measurement is 0.1 millimeters.
To find the precision for each measurement, we need to determine the smallest increment that can be measured or reported for each value.
1) 120 meters: The precision for this measurement depends on the measuring instrument used. Let's assume that the measurement was made using a standard metric ruler with millimeter markings. Since a meter is made up of 100 centimeters, and a centimeter is made up of 10 millimeters, we can convert 120 meters to millimeters: 120 meters x 100 centimeters/meter x 10 millimeters/centimeter = 120,000 millimeters. In this case, the precision is 1 millimeter since that's the smallest unit on the ruler.
2) 7 1/4 inches: The precision for this measurement is given by the fractional part (1/4 inch). Since there are 4 quarters in an inch, the precision is 1/4 inch or 0.25 inches.
3) 30.0 millimeters: The precision for this measurement is indicated by the number of decimal places. In this case, the precision is 0.1 millimeters since the measurement is given to one decimal place.
To summarize:
- 120 meters has a precision of 1 millimeter.
- 7 1/4 inches has a precision of 1/4 (or 0.25) inches.
- 30.0 millimeters has a precision of 0.1 millimeters.
