Answer 3

To subtract mixed fractions, we need to convert them into improper fractions, find a common denominator, and then subtract the fractions.

Let's start with the first mixed fraction:

11 5/18

To convert it into an improper fraction, we multiply the whole number (11) by the denominator of the fractional part (18) and add the numerator (5) to get the new numerator:

11 * 18 = 198 198 + 5 = 203

So, 11 5/18 is equivalent to the improper fraction 203/18.

Now let's move on to the second mixed fraction:

10 31/54

Converting it into an improper fraction:

10 * 54 = 540 540 + 31 = 571

So, 10 31/54 is equivalent to the improper fraction 571/54.

Now, we subtract the two fractions:

203/18 - 571/54

To find a common denominator, we need to find the least common multiple (LCM) of 18 and 54, which is 54.

Now, let's express both fractions with a denominator of 54:

(203/18) * (3/3) = 609/54 571/54

Now we can subtract:

609/54 - 571/54 = (609 - 571)/54 = 38/54

The fraction 38/54 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

38/54 ÷ 2/2 = 19/27

Therefore, 11 5/18 - 10 31/54 equals 19/27.
