Answer 2

To simplify the given expression, you should perform the operations step by step according to the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction). Here's the calculation:

1. Calculate each fraction within parentheses:

   a) 11.7/10 = 1.17 b) 5.7/30 = 0.19 c) 3.4/15 = 0.2267 d) 9.14/15 = 0.6093 e) 2.1/5 = 0.42 f) 4.7/10 = 0.47

2. Now, calculate the expression step by step:

   a) 1.17 - 0.19 = 0.98 b) 0.98 - 0.2267 = 0.7533 c) 0.6093 - 0.42 = 0.1893 d) 0.1893 - 0.47 = -0.2807

So, the result of the given expression is approximately -0.2807.
