Use ________ as the numerator because they are the ________ to the ________ of the ________ point. Therefore, ___________ is the fraction equivalent to 0.25. Write a fraction equivalent for the decimal in each box.For each decimal converted to a fraction, use the _________ _________ of the digit farthest to the right of the _________ _________ as the denominator.

The quotient is ______.Therefore, ________ is the decimal equivalent to .Then, convert the ________ to a ________.Move the ________ ________ two places to the ________.Put a ________ sign after the number. The decimal point can be omitted if it is to the right of all the digits.Therefore, ________ is the percent equivalent to 0.75, and therefore is the percent equivalent to the fraction ________.
