Answer 1

To find the common denominator of fractions, the LCM process is used.

To illustrate;

`(1)/(3)+(1)/(5)`

Note that the denominators of both fractions are different, that is, 3 and 5.

To solve this kind of math problem, the first step is to take a common denominator for both fractions. In this example, a common multiple for 3 and 5 would now be 15 (that is, the least of ALL possible multiples of 3 and 5)

Hence, the next step would be to apply the LCM to the denominators of both fractions, as follows;

`\begin{gathered} (1)/(3)+(1)/(5) \\ \text{now becomes,} \\ (5)/(15)+(3)/(15) \\ \text{And finally,} \\ (8)/(15) \end{gathered}`

The word to fill into the gap in your question is COMMON.

You need to find the "common" denominator
