1. 1/18 2. 2

1.) We are given the operation of subtraction between two fractions: 2/9 and 1/6. At first, denominators are made the same by recognizing 54 as common as nine goes in it six times and six goes in it nine times. Subtracting 1/6 (which is equivalent to 9/54) from 2/9 (which is equivalent to 12/54), we get 3/54. Simplifying 3/54 gives us 1/18.2.) The second question involves the subtraction of the fractions 5/2 and 1/2. Being under the same denominator already, the subtraction is simple. Subtracting 1/2 from 5/2 gives 4/2. And 4/2 simplifies to 2.
