Answer 2

To perform the given arithmetic calculation, let's convert the mixed fractions into improper fractions first:

7 and 5/18 can be written as (7 * 18 + 5) / 18 = 131 / 18

3 and 2/27 can be written as (3 * 27 + 2) / 27 = 83 / 27

11/54 remains the same.

Now, let's subtract these fractions:

(131/18) - (83/27) - (11/54)

To subtract fractions, we need to have a common denominator. In this case, the least common multiple (LCM) of 18, 27, and 54 is 54.

Converting all the fractions to have a denominator of 54:

(131/18) * (3/3) = 393/54 (83/27) * (2/2) = 166/54 11/54 remains the same

Now, subtracting the fractions:

(393/54) - (166/54) - (11/54) = (393 - 166 - 11) / 54 = 216/54 = 4

Therefore, 7 and 5/18 - 3 and 2/27 - 11/54 is equal to 4.
