Is it true that an answer is as precise as the most precise measurement from which it was calculated?
No. An answer is only as precise as the least precise measurement from which it was calculated.
What determines the precision of a calculated result based on measurement's?
the precision of the least precise measuement

What does it mean to round to the least precise measurement?
Round to whatever non-zero digit is farthest to the left.
Why can't we write numbers with as many significant figures as we want?
Because some part of your equation has a figure that limits how many sig figs you can use. Remember the number of sig figs is symbolic of how precise the initial measurements were. For example the number 2.4 is not as precise as 2.45298. So your answer can only be as precise as the LEAST precise measurement you have taken or been given. So in my example above if 2.4 is the least precise measurement then you can only have an answer with two sig figs.
How is the precision of a calculated result related to the precision of the measurements used in the calculation?
the precision of the answer must have the same number of significant digits as the measurement with the least significant digits- the site explains the rules and how to identify significant digits
Which piece of lab equipment would be least useful in finding the precise density of an unknown liquid?
Electronic balance
How is the precision of a Calculator result related in the precision of the measurement used in the calculation?
The precision of a calculated answer is limited by the least precise measurements used in the calculation.
When multiplying and diving measured quantities the number of significant figures in the result should be equal to the number of significant figures in?
The final answer.is only as accurate as the least accurate component in the calculation, so use the significant figures of the measurement with the fewest.
Why when you make measurements should the answer only have the same number of significant figures as the measurement with the fewest significant figures?
This is because the uncertainty in your answer is determined by the least precise measurement. It's no use expecting your answer to be known to 4 decimal places if you are only measuring to the nearest whole mile.
