The quiz input field is labeled “Type a number,” but it only accepts fraction/decimal answers typed in words (e.g., “one tenth,” “one hundredth”) and does not accept numeric formats like 1/10, 1/100, 0.1, or 0.01(Web-Desktop/Andriod)

Steps to Reproduce:

1. Go to https://www.oppia.org/create/l0S8zoUrVQNd#/preview/Introduction
2. Navigate to the question with the "Type a number" input field that expects answers like "one tenth" or "one hundredth."
3. Enter the answer as a numeric fraction or decimal (e.g., 1/10, 0.1, 1/100, 0.01) → input is not accepted.
4. Enter the answer as letters/words (e.g., "one tenth," "one hundredth") → accepted. Creating user confusion about what format to enter.
