Answer 2

Looks like a math problem! Let's break it down step by step:

(19 5/21 - 18 3/14) - 6 5/7

First, let's subtract the whole numbers:

19 - 18 = 1

Now, let's deal with the fractions:

5/21 - 3/14

To subtract fractions, we need a common denominator. The common denominator here is 42. So:

(5/21) * (2/2) = 10/42

(3/14) * (3/3) = 9/42

Now, subtract the fractions:

10/42 - 9/42 = 1/42

Now, put it all together:

1 (1/42) - 6 5/7

To subtract the mixed numbers, you can borrow from the whole number:

1 - 1 = 0 (borrow 1 from the whole number)

1 + 7/7 = 8/7

So, the result is:

-5 8/7 (or -6 1/7)

Did I get that right?
