Refers to the degree of exactness. The marks on a scale or other instrument tell you the precision that is possible.

What is the greatest precision possible with each ruler? Count the lines between the whole numbers to find the precision.

Choose the more precise measurement. Since the units are the same, we look at the decimal place. The number with the most decimal places is the most precise.

Choose the more precise measurement. Since the units are the same, we look at the decimal place. The number with the most decimal places is the most precise.

Choose the more precise measurement. Since the units are the different, we choose the smallest unit.

Find each sum or difference. Round your answer appropriately. Since 45 m is less precise than 0.9 m, round to the nearest whole number. The difference is…

Find each sum or difference. Round your answer appropriately. Since 11.4 g is less precise than 2.65 g, round to the nearest tenth. The sum is…
