Answer:
[tex]\frac{19}{8}[/tex]
Step-by-step explanation:
As per definition of commutative property, the final output of addition remains same regardless to what order the number are added in i.e.
[tex]a + b + c = b + c + a = c + a + b[/tex]
∴[tex]\frac{1}{2} + \frac{3}{8} + \frac{3}{2} = \frac{4 + 3 + 12}{8} = \frac{19}{8}[/tex]
