Question

What is the sum of 12/20 and 13/20?

Answer 1

To find : sum of rational numbers $\frac{12}{20}$ and $\frac{13}{20}$

Solution:

• As per given condition we write , $\frac{12}{20}+\frac{13}{20}$

• Properties of addition are as follows
• 1. Identity property of zero.
• 2. Inverse property.
• 3. Commutative property.
• 4. Associative property.
• Solving given expression ,

• $\frac{12}{20}+\frac{13}{20}$

     $= \frac{12 + 13}{20} \\= \frac{25}{20} \\= \frac{5}{4}$

Hence , sum of  $\frac{12}{20}$ and $\frac{13}{20}$ is $\frac{5}{4}$ .

Hence, sum of $\frac{17}{12}$ and $\frac{35}{8}$ is $\frac{139}{24}$.
