To solve the equation w - 5 2/5 = 3 1/4, we first need to convert the mixed fractions into improper fractions.

The mixed fractions 5 2/5 and 3 1/4 can be written as improper fractions as follows:

5 2/5 = (5 * 5 + 2) / 5 = 27/5
3 1/4 = (3 * 4 + 1) / 4 = 13/4

Now, we can rewrite the equation as: w - 27/5 = 13/4

To eliminate the fractions, we can multiply both sides of the equation by the LCD (Least Common Denominator) which is 20.

20 * (w - 27/5) = 20 * (13/4)
20w - 540/5 = 260/4
20w - 108 = 65

Next, we can simplify the equation by adding 108 to both sides:

20w - 108 + 108 = 65 + 108
20w = 173

Now, we can solve for w by dividing both sides of the equation by 20:

w = 173/20

We can simplify this fraction by finding the greatest common divisor (GCD) of 173 and 20, which is 1. Divide both the numerator and the denominator by 1 to simplify the fraction:

w = 173/20 = 8 13/20

Therefore, the solution to the equation w - 5 2/5 = 3 1/4 is w = 8 13/20.
