Which is greater 81 over 105 or 221 over 300?
Convert both to decimal, and compare. For example, divide 81 / 105, and write down the decimal equivalent; the same for the other fraction. OR: Find a common denominator, and convert both to the common denominator. It need not be the least common denominator; any common denominator will do - for example, if you multiply 105 x 300, you have a common denominator (which is not the least common denominator in this case). The decimal method is much easier, by the way.

Which fraction is greater 28 over 81 or 7 over 24?
To compare the fractions 28/81 and 7/24, we need to find a common denominator. In this case, the least common multiple of 81 and 24 is 81. We then convert both fractions to have a denominator of 81: 28/81 = 28/81 and 7/24 = 21/81. Now that both fractions have the same denominator, we can compare the numerators directly. Since 28 is greater than 21, the fraction 28/81 is greater than 7/24.
