It is balanced; however, some profs are not impressed with fractional numbers (but thermo profs always allow them).
Generally assume that fractions are not allowed when balancing chemical equations.
There are a few exceptions, such as when the chemical equation is an intermediate step as part of a calculation, such as a thermochemical calculation as DrBob says. Another is where there is water of crystallization.
Outside of chemistry, biologists and earth scientists will use fractions and even decimals.
