Calculation of 18/19-(8/19+7/38)

To solve the expression 18/19-(8/19+7/38), we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, we need to simplify the expression inside the parentheses: 8/19 + 7/38 = (8/19) + (7/38)

Now, we can add the fractions inside the parentheses: (8/19) + (7/38) = (8/19) + (14/38) = (8/19) + (7/19) = 15/19

So, the expression becomes: 18/19 - 15/19

Now, we can subtract the fractions: 18/19 - 15/19 = (18 - 15)/19 = 3/19

Therefore, the value of 18/19-(8/19+7/38) is 3/19.
