\(\tfrac{7}{12}+\tfrac{11}{12}=\tfrac{3}{2}\).
Step 1: Check denominators
Both fractions have the same denominator: \(12\). So we can add the numerators.
Step 2: Add the numerators
\(7+11=18\)
Step 3: Write the sum
\(\tfrac{7}{12}+\tfrac{11}{12}=\tfrac{18}{12}\)
Step 4: Simplify the fraction
Both \(18\) and \(12\) are divisible by \(6\).
\(\tfrac{18\div6}{12\div6}=\tfrac{3}{2}\)
Step 5: Conclude
So, \(\tfrac{7}{12}+\tfrac{11}{12}=\tfrac{3}{2}\).
(Extra: \(\tfrac{3}{2}\) is the same as \(1\tfrac{1}{2}\).)
