Question

What is equivalent to xy/a - 1/b

Answer 1

The steps in achieving the answer for the simplification are as follows:

1. The least common multiple of the denominators of the terms of the given is ab.

2. Multiply the expression with ab, such that,

                              (xy/a - 1/b) x (ab)

3. Simplifying,
                                 xyb - a

4. Writing ab as the denominator of the expression in number, we get the final answer which is equal to,
                               (xyb - a)/ab
