One fluid ounce is equivalent to 0.0078125 US liquid gallon. How do you write 0.0078125 in scientific notation

Answer 1

To write the number 0.0078125 in scientific notation, you'll want to express it as a number between 1 and 10, multiplied by a power of 10.

In this case, you would move the decimal point six places to the right to get the number 7.8125. Since you moved the decimal six places, you'll be using 10 to the negative sixth power to show that the original number is much smaller than the number you've created by moving the decimal point.

So, the scientific notation for 0.0078125 is:

7.8125 × 10^(-6)
