Answer

Explanation:

Step1: Add the numbers and round according to the rule

For (704.09\ g+8.0320000\ g), add them: (704.09 + 8.0320000=712.122\ g). The number with the fewest decimal - places is (704.09) (two decimal places), so the answer is (712.12\ g).

Step2: Add the numbers and round according to the rule

For (5.3025\ mL + 1.0\ mL), add them: (5.3025+1.0 = 6.3025\ mL). The number with the fewest decimal - places is (1.0) (one decimal place), so the answer is (6.3\ mL).

Step3: Subtract the numbers and round according to the rule

For (9.70\ kg−3.541\ kg), subtract them: (9.70 - 3.541=6.159\ kg). The number with the fewest decimal - places is (9.70) (two decimal places), so the answer is (6.16\ kg).

Step4: Add the numbers and round according to the rule

For (7.801\ mm+231.6\ mm), add them: (7.801 + 231.6=239.401\ mm). The number with the fewest decimal - places is (231.6) (one decimal place), so the answer is (239.4\ mm).

Answer:

  1. (712.12\ g)
  2. (6.3\ mL)
  3. (6.16\ kg)
  4. (239.4\ mm)
