Answer 2

To solve the given expression, we'll follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's break it down step by step:

1. Calculate each multiplication first:

   • 15 23/27 * 17 11/16 = (15 + 23/27) * (17 + 11/16)
   • 17 + 11/16 = (17 * 16 + 11) / 16 = (272 + 11) / 16 = 283 / 16
   • 15 + 23/27 = (15 * 27 + 23) / 27 = (405 + 23) / 27 = 428 / 27
   • Now, multiply the two results: (428 / 27) * (283 / 16) = (428 * 283) / (27 * 16)

2. Calculate each subtraction:

   • 11 16/27 * 17 11/16 = (11 + 16/27) * (17 + 11/16)
   • Calculate (17 + 11/16) as we did before: (17 * 16 + 11) / 16 = 283 / 16
   • Calculate (11 + 16/27) similarly: (11 * 27 + 16) / 27 = (297 + 16) / 27 = 313 / 27
   • Now, multiply the two results: (313 / 27) * (283 / 16) = (313 * 283) / (27 * 16)

3. Calculate the final subtraction:

   • 4 7/27 * 16 11/16 = (4 + 7/27) * (16 + 11/16)
   • Calculate (16 + 11/16) as we did before: (16 * 16 + 11) / 16 = 267 / 16
   • Calculate (4 + 7/27) similarly: (4 * 27 + 7) / 27 = (108 + 7) / 27 = 115 / 27
   • Now, multiply the two results: (115 / 27) * (267 / 16) = (115 * 267) / (27 * 16)

Now, we'll subtract the results we obtained from the two subtractions (step 2 and step 3) from the result of the multiplication (step 1):

Result = (428 * 283) / (27 * 16) - (313 * 283) / (27 * 16) - (115 * 267) / (27 * 16)

To further simplify this expression, we can factor out (283 / (27 * 16)):

Result = (283 / (27 * 16)) * (428 - 313 - 115)

Now, let's calculate the subtraction inside the parentheses:

Result = (283 / (27 * 16)) * (428 - 428)

Since (428 - 428) equals 0, the entire expression will be equal to 0:

Result = 0
