Hi, during the following sentence from "Chinese growth is losing altitude" from www.Economist.com, I think that "a" is superfluous. Am I wrong? Thanks for your explanation.

The darkest cloud over China is its property market. Factoring in its impact from steel to furniture, it has powered nearly a fifth of the economy.

    You must have "a fifth." Although you could use "one-fifth" without an "a" – but I wouldn't; it's not as smooth.
