Answer 3

To calculate the expression (3 1/6 - 1/8) * (21/4 - 1/2), you can follow these steps:

Step 1: Convert mixed numbers to improper fractions: 3 1/6 = 19/6 21/4 = 105/6

So, the expression becomes: (19/6 - 1/8) * (105/6 - 1/2)

Step 2: Find the common denominators: The common denominator for both fractions in each part of the expression is 48. So, we need to rewrite the fractions with a common denominator of 48.

(19/6 - 1/8) becomes (152/48 - 3/48) (105/6 - 1/2) becomes (280/48 - 24/48)

Now, the expression looks like this: (152/48 - 3/48) * (280/48 - 24/48)

Step 3: Perform the subtraction within each part: (152/48 - 3/48) = 149/48 (280/48 - 24/48) = 256/48

Now, the expression is: (149/48) * (256/48)

Step 4: Multiply the fractions: (149/48) * (256/48) = (149 * 256) / (48 * 48) = 38144/2304

Step 5: Simplify the fraction, if possible: To simplify the fraction, you can find the greatest common divisor (GCD) of the numerator and denominator, which is 16. Divide both the numerator and denominator by 16:

(38144/16) / (2304/16) = 2384/144

Now, simplify further by finding the GCD of 2384 and 144, which is 16:

(2384/16) / (144/16) = 149/9

So, the simplified result of the expression is 149/9.
