The answer depends on what the starting expression is. It is not easy to generate an equivalent expression for trigonometric functions, for example, without using an infinite series of exponents.

Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
9/12 is greater.
The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.
Reducing equivalent fractions to their simplest form.
Equivalent ratios are like equivalent fractions because they represent the same relationship between quantities in different forms. Just like equivalent fractions are different expressions of the same value, equivalent ratios show the same comparison between two quantities using different numerical values.
Finding the GCF will help in simplifying fractions. Finding the LCM will help in adding and subtracting fractions.

Finding the LCM will make adding and subtracting fractions easier.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.
