3️⃣ Real-Life Conversations with Big Numbers

Part 1 — Eric and Juliana: Professional Sports Salaries

Eric: I read that some professional athletes earn more than $40,000,000 a year.
Juliana: $40,000,000? That number is hard to imagine.
Eric: One player had a contract worth $325,000,000.
Juliana: $325,000,000 is more than many cities spend on schools.
Eric: The salary sounds huge, but the team may earn billions from tickets, television, and advertising.
Juliana: So the numbers are not only about sports. They are also about business.

Practice: Write 325,000,000 in words.

Part 2 — Nicely and Neima: Home Prices

Nicely: I saw a small house listed for $425,000.
Neima: $425,000 is a lot of money.
Nicely: In some cities, a simple apartment can cost $850,000.
Neima:$850,000? That sounds impossible for many families.
Nicely: Yes. Home prices are a real-life reason to read large numbers carefully.
Neima: A comma can change everything. 85,000 is very different from 850,000.

Practice: Write 850,000 in words.

Part 3 — Javier and Sofia: Movie Budgets

Javier: Did you know some big movies cost more than $200,000,000 to make?
Sofia: $200,000,000 ? That is like a sports salary, a school budget, and a hospital project together.
Javier: And if the movie is popular, it might earn $1,000,000,000 around the world.
Sofia: One billion dollars is a giant number.
Javier: That is why commas help. They show if we are reading thousands, millions, or billions.
Sofia: Big numbers are easier when we read one group at a time.

Practice: Write 1,000,000,000 in words.
