add or subtract the following measurements. be sure each answer you enter contains the correct number of significant digits.\n8.677 ml + 13.97 ml =\n5.970 ml - 4.60 ml =\n15.7 ml + 3.927 ml =

Answer

Explanation:

Step1: Add 15.7 ml and 3.927 ml

$15.7+3.927 = 19.627$. Since 15.7 has one - decimal place, we round to one - decimal place. So the result is 19.6 ml.

Step2: Subtract 4.60 ml from 5.970 ml

$5.970 - 4.60=1.37$. Since 4.60 has two - decimal places, we keep two - decimal places. So the result is 1.37 ml.

Step3: Add 8.677 ml and 13.97 ml

$8.677+13.97 = 22.647$. Since 13.97 has two - decimal places, we round to two - decimal places. So the result is 22.65 ml.

Answer:

19.6 ml 1.37 ml 22.65 ml
