slega [8]

What we know:
-volume of 10,000 drops is 10 fluid ounces

Step 1: Divide 10,000 by 10 (to find how much we need to divide 10 by to get our answer)

10,000/10=1,000

Step 2: Divide 10 by 1,000 (to find our answer)

10/1,000=0.01

Our answer is 0.01. The volume of 10 drops of liquid is 0.01 fluid ounces.
