Answer 3

To solve this expression, you need to add the fractions inside the parentheses and then multiply the result by 2. Here's how you can do it step by step:

1. Add the fractions inside the parentheses: 1/2 + 1/3 + 1/4 + 1/5 + 1/6

To add these fractions, you need to find a common denominator, which is the least common multiple of 2, 3, 4, 5, and 6, which is 60. Then, you can rewrite each fraction with a denominator of 60:

1. 1/2 = 30/60
2. 1/3 = 20/60
3. 1/4 = 15/60
4. 1/5 = 12/60
5. 1/6 = 10/60

Now, add these fractions:

30/60 + 20/60 + 15/60 + 12/60 + 10/60 = (30 + 20 + 15 + 12 + 10) / 60 = 87/60

2. Multiply the sum by 2:

2 * (87/60) = (2 * 87) / 60 = 174/60

Now, you can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 6:

(174 ÷ 6) / (60 ÷ 6) = 29/10

So, the value of the expression is 29/10 or 2.9 when expressed as a decimal.
