Answer 3

Certainly! To add fractions with different denominators, you first need to find a common denominator. In this case, the common denominator for 12 and 15 is 60. Here's how you can add $\frac{7}{12}$ and $\left(-\frac{13}{15}\right)$ using a common denominator of 60:

$\frac{7}{12}$ can be converted to an equivalent fraction with a denominator of 60 by multiplying both the numerator and denominator by 5: $\frac{7 \times 5}{12 \times 5} = \frac{35}{60}$.

$-\frac{13}{15}$ can be converted to an equivalent fraction with a denominator of 60 by multiplying both the numerator and denominator by 4: $-\frac{13 \times 4}{15 \times 4} = -\frac{52}{60}$.

Now, you can add $\frac{35}{60}$ and $-\frac{52}{60}$ to get:

$\frac{35}{60} + \left(-\frac{52}{60}\right) = \frac{35 - 52}{60} = -\frac{17}{60}$

So, $\frac{7}{12} + \left(-\frac{13}{15}\right) = -\frac{17}{60}$.
