Answer: Third option.
Explanation:
By definition, fractions have the following form:
Where "a" is the Numerator and "b" is the Denominator. Both are Integers and
Given the following expression provided in the exercise:
You can notice that the denominators of the fractions are different.
Therefore, in order to add the fractions, you can follow the steps shown below:
Step 1. You must find the Least Common Denominator. Since 2, 5 and 3 are Prime numbers, this is:
Step 2. Now you have to divide each original denominator by the LCD and multiply the corresponding numerators by that quotient:
Step 3. And finally you must solve the addition, getting the following result:
