Answer 2

To solve the expression (205/404 - 306/509) - 19, we can follow the order of operations (also known as PEMDAS or BODMAS) to simplify the expression step by step.

Step 1: Simplify the fractions

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 404 * 509 = 205636. Let's simplify the fractions first:

205/404 = 50525/100000 306/509 = 155754/255131

Now we can rewrite the expression as:

(50525/100000 - 155754/255131) - 19

Step 2: Subtract the fractions

To subtract the fractions, we need to have the same denominator. Since the denominators are already different, we can multiply the numerators and denominators of each fraction by the other fraction's denominator to get a common denominator:

(50525 * 255131 - 155754 * 100000) / (100000 * 255131)

Now we can simplify the numerator:

(12884910275 - 15575400000) / (100000 * 255131) = (-2690489725) / (25513100000)

Step 3: Subtract 19

Now we can subtract 19 from the fraction:

(-2690489725) / (25513100000) - 19

To subtract a fraction from a whole number, we need to convert the whole number to a fraction with the same denominator. In this case, the denominator is 25513100000:

19 = 19 * 25513100000 / 25513100000 = 484748900000 / 25513100000

Now we can rewrite the expression as:

(-2690489725) / (25513100000) - (484748900000 / 25513100000)

Step 4: Combine the fractions

To subtract the fractions, we need to have the same denominator. Since the denominators are already the same, we can subtract the numerators:

(-2690489725 - 484748900000) / (25513100000) = -487439389725 / 25513100000

So the simplified expression is -487439389725 / 25513100000.

Please note that the above calculation is based on the given expression and the order of operations. If there is any ambiguity in the expression or if the expression is different, the result may vary.
