- When to spell out numbers [duplicate] 2 answers
I've just read this in a review:
Thankfully, the energy efficient Qualcomm chip helped the handset reach a best-ever score of 17 hours and 30 minutes in our continuous video rundown test. Compared to the outgoing model, which lasted ten hours 43 minutes in the same test
The first part uses 17 hours while the second part uses ten hours. Which is correct? What are the rules to determine when which should be used?
