Answer 3

To add the two mixed numbers, you can follow these steps:

Step 1: Add the whole numbers together. 9 + (-6) = 3

Step 2: Add the fractions together.

13/40 + 11/35

To add fractions, you need to find a common denominator. In this case, the least common denominator is 280.

Now, let's rewrite the fractions with a common denominator:

(13/40) * (7/7) = 91/280 (11/35) * (8/8) = 88/280

Step 3: Add the fractions with the common denominator:

91/280 + 88/280 = (91 + 88) / 280 = 179/280

Step 4: Combine the whole number and the fraction:

3 + 179/280

So, the result is 3 179/280 or 3.63928571 (rounded to 8 decimal places).
