Steps
1. As we are having different denominators,
2. We have to take LCD of them, by listing multiple as shown
•
• The LCD is
3. As the denominator is changed, then the numerator also to be changed by the same number, then
•
4. As the denominator of the second fraction is 14, no need to change
5. Now denominators are common, then add numerator
•
Hence, the sum of the fraction is .
