36/12+9/12

To simplify the expression \( \frac{36}{12} + \frac{9}{12} \):

1. Calculate \( \frac{36}{12} \): \[ \frac{36}{12} = 3 \]

2. The second fraction \( \frac{9}{12} \) can also be simplified: \[ \frac{9}{12} = \frac{3}{4} \]

3. Now, add the two results: \[ 3 + \frac{3}{4} \]

4. To add these, convert 3 to a fraction with a denominator of 4: \[ 3 = \frac{12}{4} \]

5. Now, add the fractions: \[ \frac{12}{4} + \frac{3}{4} = \frac{12 + 3}{4} = \frac{15}{4} \]

So, the final result is: \[ \frac{15}{4} \text{ or } 3.75 \]
