Answer 2

18 + 5/79 - (17 + 5/79 + 3/4)

First, let's simplify the expression inside the parentheses: 17 + 5/79 + 3/4 To add the fractions, we need to find a common denominator. The common denominator for 79 and 4 is 316. So, 5/79 is equivalent to 20/316 and 3/4 is equivalent to 237/316. Now we can add the fractions: 17 + 20/316 + 237/316 = 17 + 257/316

Now we can substitute this back into the original expression: 18 + 5/79 - (17 + 257/316)

To subtract the expression inside the parentheses, we need to find a common denominator. The common denominator for 79 and 316 is 24844. So, 5/79 is equivalent to 24844/79 and 257/316 remains as is. Now we can subtract the fractions: 18 + 24844/79 - 17 - 257/316 = 1 + 24844/79 - 257/316

To subtract the fractions, we need to find a common denominator. The common denominator for 79 and 316 is 24844. So, 24844/79 remains as is and 257/316 is equivalent to 257*79/316*79 = 20343/24844. Now we can subtract the fractions: 1 + 24844/79 - 20343/24844 = 1 + (24844*24844 - 20343*79)/(79*24844) = 1 + (617862736 - 1605697)/1970476 = 1 + 616257039/1970476

So, the final result is: 1 + 616257039/1970476
