Answer 2

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

1. First, let's calculate the product of 5.25 and 2: 5.25 x 2 = 10.50

2. Next, let's convert the mixed number 2 2/7 into a decimal. To do this, we need to convert the mixed number into an improper fraction: 2 2/7 = (2 x 7 + 2) / 7 = 16/7

3. Now, let's subtract 7.05 from the result obtained in step 2: 16/7 - 7.05 = (16 - 7.05 * 7) / 7

Performing the calculations: (16 - 49.35) / 7 = -33.35 / 7

Finally, we can simplify the fraction: -33.35 / 7 = -4.764285714285714

Therefore, the result of the given expression is approximately -4.764285714285714.
