To convert a decimal to a common fraction, multiply the decimal by a whole number equal to the desired denominator of the fraction. Point off as many decimal places as were in the decimal. If the decimal part of the answer is 0.5 or more, add one to the whole number. Place over the desired denominator.Example:Change 0.125 to eighths0.125 × 8 = 1.000 = 1/8Convert the following and match with the correct answer shown below:I. 1/16II. 11/32III. 17/32IV. 23/32V. 5/16VI. 7/16VII. 3/8VIII. 7/8

When multiplying two fractions, multiply the numerator of one fraction by the ? of the second fraction. This product is placed over the product of the two denominators.

The correct answer is: numerator

To change a mixed number to an improper fraction, multiply the denominator of the fraction by the ? and add the ? of the fraction. Place this value over the denominator to make the improper fraction.
