Percent question: Is it correct?

Please clarify whether the following are correct is US books:

1. rate of two percent (or) rate of 2 percent

2. label is typically only 30-50 percent (or) label is typically only 30 percent to 50 percent

Good morning :)

1) Should be: "rate of 2 percent"
2) Should be: "Label is typically only thirty to fifty percent

The general rule of thumb is that if it is under ten, you can use the numeral; if it is ten or over, write out the words.

Hope this helps!

Good morning.

Thanks, I am confused. According to the US specification it states "Use numerals for 10 and above". Please clarify.

Good morning :)

You must be using the APA reference style; in that case, all numbers contained in mathematical functions and/or formulas (including percentages) should be written as numerals. If you are writing in another reference style, those rules will change; since you didn't specify in your last post, it is difficult for me to tell which you are using, hence my reference to a "general rule of thumb".
