Since the numerator and denominator share no common positive integer factors other than 1, 81/100 is already expressed in its simplest form.

It is: 324

The lcm or lcd is 5751

LCD(9, 16, 18, 81) = 1296

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.

It is 100
