Normally one decimal place is appropriate.
It should be moved 4 places.
The number of decimal places in the product must equal the total number of decimal places in the factors. John's product should have 2 decimal places.
When adding measurements, the result should be reported with the same number of decimal places as the measurement with the fewest decimal places. In this case, 11.074 mm has three decimal places, while the second measurement is unspecified. Assuming the second measurement has no decimal places, the result should be rounded to zero decimal places, thus reported as 11 mm. If the second measurement has decimal places, adjust accordingly based on that.
The answer depends on how many decimal places are in the summands.
When performing addition, the result should be reported with the same number of decimal places as the measurement with the fewest decimal places. The number 8.52010 has five decimal places, while 1.93 has two. Therefore, the result should be rounded to two decimal places, leading to a final answer of 10.45, which has four significant figures.
The answer depends on the graduation on the flask.
Traditionally, 2 decimal places should be used to record the volume of a 10 ml volumetric flask. Recording the volume 2 decimal places means that you are measuring, or rounding your measurement, to the hundredth decimal place, whereas if you were measuring just 1 decimal place, you'd be measuring the tenth decimal place. When we say 2 decimal places, we mean that there should be two numbers that come after the decimal point, regardless of whether or not there is a number that is standing in front (or visually, to the left) of the decimal point.

The number of decimal places has no bearing on the relative value. 0.2 is greater than 0.137 0.402 is greater than 0.3

Move the decimal 2 places to the left which should get you 0.008
Move the decimal 2 places to the left which should get you 0.028

When working with decimals, the primary rules include aligning the decimal points when adding or subtracting, which ensures accurate placement of values. For multiplication, the total number of decimal places in the product should equal the sum of the decimal places in the factors. In division, the divisor should be made a whole number by moving the decimal point, and the same number of places should be moved in the dividend. Lastly, rounding rules apply when necessary, typically rounding to a specified number of decimal places.
