7 points!!!! hep help help 2. When you are converting a decimal to a fraction, how do you know what to use as the denominator?
vitfil [10]

Step-by-step explanation:

Check to see if there is a number before (to the left of) the decimal. If there is, this number is the whole number of the fraction. So, 3 is the whole number. Place the number that falls after (to the right of) the decimal in the numerator; then use the decimal placement to determine the denominator.
