Answer 3

To perform this arithmetic calculation, you can follow these steps:

Step 1: Convert all mixed numbers into improper fractions. Step 2: Find a common denominator for all fractions. Step 3: Perform the subtraction. Step 4: Simplify the result if necessary.

Let's break down each step:

Step 1: Convert mixed numbers to improper fractions:

• 5/18 is already a fraction.
• 3 2/27 = (3 * 27 + 2)/27 = (81 + 2)/27 = 83/27
• 11/548 is already a fraction.
• 7/12 is already a fraction.
• 4 18/5 = (4 * 5 + 18)/5 = (20 + 18)/5 = 38/5
• 1 1/4 = (1 * 4 + 1)/4 = (4 + 1)/4 = 5/4

Step 2: Find a common denominator. The common denominator for all the fractions is 27, as it is a common multiple of all the denominators.

Step 3: Subtract the fractions:

(5/18) - (83/27) - (11/548) - (7/12) - (38/5) - (5/4)

Now, make sure all fractions have the same denominator (27):

(5/18) - (83/27) - (11/548) - (7/12) - (38/5) - (5/4) = (5/18) - (83/27) - (11/548) - (63/108) - (2052/108) - (135/108)

Step 4: Simplify the fractions:

Now that we have a common denominator, we can subtract:

(5/18) - (83/27) - (11/548) - (63/108) - (2052/108) - (135/108)

To subtract the fractions, combine the numerators:

(527 - 8318 - 112 - 631 - 20521 - 1351)/27*18

Calculate the numerator:

(135 - 1494 - 22 - 63 - 2052 - 135)/(27*18)

Now, combine the terms in the numerator:

(-3631)/(27*18)

Finally, simplify the fraction:

(-3631)/(27*18) = -3631/486

You can simplify this fraction further by dividing both the numerator and denominator by their greatest common divisor, which is 17:

(-3631/17)/(486/17) = -213/27

So, the result of the subtraction is:

-213/27 = -71/9
