Question

perform the following operation: 16.1 ml - 6.81 ml - 0.00032 ml.
9.2 ml
9.3 ml
9.29 ml
9.2897 ml

Explanation:

Step1: First subtract 6.81 mL from 16.1 mL

$16.1 - 6.81=9.29$ mL

Step2: Then subtract 0.00032 mL from the result

$9.29 - 0.00032 = 9.28968$ mL

Step3: Round the result to one - decimal place

Since the digit in the second - decimal place is 8 which is greater than 5, we round up. So $9.28968\approx9.3$ mL

Answer:

9.3 mL
