Travel or Travelling

Do i say “10% travel is required” or “10% travelling is required”? And why?

It does not make sense as it stands, Jolyn. What is the context? A job description? A discount tour?

Job description. i always come across it.

But usually i would say “need to travel 10% of the time”.

Interesting. This is the first time I see the expression ‘need to travel 12% of the time’. Where are those job descriptions published?[YSaerTTEW443543]

TOEIC listening, question-response: How many times a day does that copier go wrong?[YSaerTTEW443543]

Then how shouldit be written?

Also, “frequent travelling” or “frequent travel”?

‘Frequent/occasional travel’ is fine. I have seen that in advertisements, and I have also seen it expressed as an estimated percentage-- though I doubt that the latter is very accurate.
