Answer 2

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

Step 1: Add the whole numbers together. Step 2: Add the fractions separately. Step 3: Combine the results from Step 1 and Step 2.

Let's break it down:

Step 1: Add the whole numbers: 4 + 2 + 5 = 11

Step 2: Add the fractions: 3/5 + 5/7 + 9/35

To add fractions with different denominators, you need to find a common denominator. In this case, the common denominator for 5, 7, and 35 is 35. Now, you'll need to rewrite each fraction with the common denominator:

3/5 = (3 * 7) / (5 * 7) = 21/35 5/7 = (5 * 5) / (7 * 5) = 25/35 9/35 (already in terms of the common denominator)

Step 2 (continued): Add the fractions with the common denominator: 21/35 + 25/35 + 9/35 = (21 + 25 + 9) / 35 = 55/35

Step 3: Combine the whole numbers from Step 1 and the fractions from Step 2: 11 + 55/35

Now, you need to simplify the fraction:

55/35 can be simplified by finding the greatest common divisor (GCD) of 55 and 35, which is 5. Divide both the numerator and denominator by 5:

(55 ÷ 5) / (35 ÷ 5) = 11/7

So, the final result is:

11 + 11/7

You can leave it as an improper fraction or convert it to a mixed number if needed:

11 + 11/7 = 11 4/7

Therefore, 4 3/5 + 2 5/7 + 5 9/35 = 11 4/7 or 11 and 4/7 when expressed as a mixed number.
