5/9 - 3/8 + (-1/4) + 1 4/9 + 1 5/8=?

3.

Step-by-step explanation:

5/9 - 3/8 + (-1/4) + 1 4/9 + 1 5/8

= 5/9 - 3/8 - 1/4 + 13/9 + 13/8

Now we find the LCM of 4, 8 and 9:

4 = 2*2

8 = 2*2*2

9 = 3*3

The LCM = 2 * 2 * 2 * 3 * 3 = 72 so we have:

40/72 - 27/72 - 18/72 + 104/72 + 117/72

= 216 / 72

= 3.

Your answer would be three. You'd have to easily just simplify the expression.
