Answer: C To find the the correct answer, you must subtract 2 3/5 from 10 1/2. (1) They are mixed fractions, so you must first convert them to improper fractions. To convert, multiply the denominator to the whole number, then add the numerator. *So for 2 3/5, when converted to improper fraction, it would be 13/5. *For 10 1/2, when converted to improper fraction, it would give you 21/2. (2) But since they have different denominators, you must now find their least common denominator to convert them to similar fractions. For this instance, the least common denominator (LCD) is 10. * 13/5 > 10 divided by 5 is 2. > 2 multiplied by 13 is 26. > That would give you 26/10 *21/2 > 10 divided by 2 is 5 > 5 multiplied by 21 is 105 > That would give you 105/10 (3) Now that they have the same denominator, you can proceed with the subtraction to find the missing number. * 105/10 minus 26/10 = 79/10 (4) Convert now 79/10 to get the mixed fraction. * Divide 79 by 10, that would give you 7 9/10.
