Answer 2

To solve this expression, let's break it down step by step:

1. Calculate the multiplication: 2.4 × 1 = 2.4
2. Calculate the multiplication: 15/12 × 1 = 15/12 = 5/4
3. Calculate the multiplication: 7/17 × 5/4 = 35/68
4. Calculate the division: 3 1/7 ÷ 1 4/7 Convert mixed numbers to improper fractions: 3 1/7 = 22/7 1 4/7 = 11/7 Now, divide: (22/7) ÷ (11/7) = 22/11 = 2

Now, let's put it all together:

2.4 + 35/68 - 2 = 2.4 + 35/68 - 2 Find a common denominator for fractions: 68 Convert 2.4 to a fraction: 2.4 = 24/10 = 240/100 Now, add and subtract fractions: (240/100) + (35/68) - 2 = (240 * 68 + 35 * 100) / (100 * 68) - 2 = (16320 + 3500) / 6800 - 2 = 19820 / 6800 - 2 = 995 / 340 - 2 ≈ 2.926 - 2 ≈ 0.926

So, the result of the expression is approximately 0.926.
