Answer 3

To solve the expression (6 1/2 - 4 1/4) / 2 1/2, we need to convert the mixed numbers into improper fractions and then perform the calculations.

Let's start by converting the mixed numbers to improper fractions:

6 1/2 = (6 * 2 + 1) / 2 = 13/2 4 1/4 = (4 * 4 + 1) / 4 = 17/4 2 1/2 = (2 * 2 + 1) / 2 = 5/2

Now we can substitute the values and solve the expression:

(13/2 - 17/4) / 5/2

To simplify this expression, we'll first find a common denominator for the fractions in the numerator:

(13/2 - 17/4) = (26/4 - 17/4) = 9/4

Now we can divide this result by the fraction in the denominator:

(9/4) / (5/2)

Dividing fractions involves multiplying the first fraction by the reciprocal of the second fraction:

(9/4) * (2/5) = (9 * 2) / (4 * 5) = 18/20

To further simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:

18/20 = (18/2) / (20/2) = 9/10

Therefore, (6 1/2 - 4 1/4) / 2 1/2 equals 9/10.
