9 11/21
114/175
7 9/26
8 25/56

The correct answer is: 114/175

To convert a decimal to a fraction, we need to look at the digits after the decimal point. In this case, the decimal is 0.724. The number 724 is in the thousandths place, so we write it as 724/1000. Then, we simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 4. 724/1000 ÷ 4/4 = 181/250. Hence, 0.724 is equivalent to 181/250 when expressed as a fraction. Options A, C, and D are incorrect because they do not accurately represent 0.724 when expressed as a fraction. Option A is a mixed number with improper fraction, option C is a mixed number with improper fraction, and option D is a mixed number with improper fraction. It is important to note that when converting a decimal to a fraction, the fraction must be in its simplest form, meaning there should be no common factors between the numerator and denominator. Thus, option B is the correct answer.
