To calculate the expression 22/8 - 3/2, we need to find a common denominator for the two fractions. First, let's simplify the fractions separately:
22/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2. Therefore, we get 11/4.
3/2 is already in its simplest form.
Now we can find the common denominator, which is the smallest multiple that 4 and 2 both divide into, which is 4.
Next, we need to adjust both fractions to have the same denominator of 4:
11/4 becomes 11/4 * 1/1 (multiplying numerator and denominator by 1 = 4/4, so the fraction remains unchanged.
3/2 becomes 3/2 * 2/2 (multiplying numerator and denominator by 2 = 6/4.
Now that we have both fractions with the same denominator, we can subtract them:
(11/4) - (6/4) = 5/4
Therefore, 22/8 - 3/2 = 5/4.
