Answer 3

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

Addition:

1. Add the whole numbers together.
2. Add the fractions together.
3. If the fraction sum is an improper fraction (numerator larger than denominator), simplify it by dividing the numerator by the denominator to get a new mixed number.

Let's apply these steps to your first expression:

Addition:

1. Add the whole numbers: 2 + 3 = 5.
2. Add the fractions: 3/11 + 1/6.

To add these fractions, you need a common denominator, which is 66 (the least common multiple of 11 and 6). So, you'll convert both fractions to have a denominator of 66:

(3/11) * (6/6) = 18/66 (1/6) * (11/11) = 11/66

3. Now, add the fractions together: 18/66 + 11/66 = 29/66.

So, 3/11 + 1/6 = 29/66.

4. Simplify the fraction if possible. In this case, it's already simplified.

Now, you have 5 (the whole number) and 29/66 as the fraction. So, the result is:

5 29/66.

Subtraction: For the subtraction, you can follow similar steps:

1. Subtract the whole numbers: 4 - 1 = 3.
2. Subtract the fractions: 1/5 - 1/15.

To subtract these fractions, you need a common denominator, which is 15 in this case:

(1/5) * (3/3) = 3/15 (1/15) * (5/5) = 5/15

3. Now, subtract the fractions: 3/15 - 5/15 = -2/15.

So, 1/5 - 1/15 = -2/15.

4. Simplify the fraction if possible. In this case, it's already simplified.

Now, you have 3 (the whole number) and -2/15 as the fraction. So, the result is:

3 - 2/15.

If you need to find the final result, subtract 2/15 from 3:

3 - 2/15 = 45/15 - 2/15 = 43/15.

So, 4 1/5 - 1 1/15 = 43/15.
