Question

7.7 billion - 18.2 million
3rd of 7.7 billion

Answer 1

To calculate the two requested values:

1. **Subtracting 18.2 million from 7.7 billion:**

- 7.7 billion = 7,700 million
- 7,700 million - 18.2 million = 7,681.8 million

So, \( 7.7 \text{ billion} - 18.2 \text{ million} = 7,681.8 \text{ million} \) or 7.6818 billion.

2. **Calculating a third of 7.7 billion:**

- 7.7 billion ÷ 3 = 2.5667 billion (approximately)

So, a third of \( 7.7 \text{ billion} \) is approximately \( 2.5667 \text{ billion} \) or \( 2,566.7 \text{ million} \).

In summary:
- \( 7.7 \text{ billion} - 18.2 \text{ million} = 7.6818 \text{ billion} \)
- A third of \( 7.7 \text{ billion} \) is approximately \( 2.5667 \text{ billion} \)
