Answer 2

To solve the expression (13/12+11/20)*12/5, we follow the order of operations:

1. First, we simplify the expressions within the parentheses: (13/12+11/20) = (260/240 + 66/240) = 326/240

2. Next, we multiply this result by 12/5: (326/240) * (12/5)

3. We can simplify by canceling out common factors between the numerator and denominator: (326/240) * (12/5) = (163/120) * (12/5)

4. Then, we multiply the numerators and denominators separately: (163 * 12) / (120 * 5) = 1956/600

5. Finally, we simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 12: 1956/600 = 163/50

Therefore, the value of the expression (13/12+11/20)*12/5 is equal to 163/50.
