Question

How do you read the numbers?

13
14
42

(Answer) thirteen, fourteen, forty-two

(Are the expressions above right? Can we ask "Write the numbers in English?" Is this question better?)

Answer 1

You can use either question. When you use the word "numbers," you are usually referring to the words. When you use the word "numerals," you are usually referring to the symbols: 1, 2, 3, etc.
