Translation of percentage in German

I am trying to learn Spanish because Spanish is becoming more and more important in the USA because of immigrants. Especially here in Texas. I used to live in Nevada for many years. Boring place, gotta tell ya.
This site is a good website for me, because I don't know many people to talk to in English. But I am at the beginning of my way, since I am mother of two and I do not have enough time to practice.
Thank you for your answer, your English is better than my Spanish. I live in Liverpool in Great Britain, that is a town around 300 kilometers north of London. My wife and I have 4 children.
