How do I write the following four sentences in romaji:

1. Is this book yours?

2. Your money is over there.

3. There is your pencil.

4. Here is your photo.

To write the given sentences in romaji, which is the romanized form of Japanese, you need to convert the sentences from Japanese script (Hiragana, Katakana, or Kanji) to the English alphabet. Here are the four sentences written in romaji:

1. Is this book yours?
Kono hon wa anata no desu ka?

2. Your money is over there.
Anata no okane wa soko ni arimasu.

3. There is your pencil.
Anata no empitsu ga arimasu.

4. Here is your photo.
Koko ni anata no shashin ga arimasu.

To romanize Japanese words, there are various systems, the most common being Hepburn Romanization. However, it's worth mentioning that "r" in romaji represents a flipped "r" sound like in the English "l."

Keep in mind that when communicating with native Japanese speakers, it is best to use the appropriate Japanese script (Hiragana, Katakana, or Kanji) rather than relying solely on romaji.
