Answer

To find out how much `1 billion` is equal to, we can break it down step by step.

### Step 1: Understand the value of 1 billion
1 billion is represented numerically as:
\[ 1 \text{ billion} = 1,000,000,000 \]

### Step 2: Convert billion to millions
We know that:
\[ 1 \text{ million} = 1,000,000 \]
To convert billion to millions, we divide the number of billions by the number of millions in a billion:
\[ 1,000,000,000 \div 1,000,000 = 1,000 \]
Thus,
\[ 1 \text{ billion} = 1,000 \text{ million} \]

### Step 3: Convert billion to lakhs (using the Indian numbering system)
In the Indian numbering system:
\[ 1 \text{ lakh} = 100,000 \]
To convert billion to lakhs, we divide the number of billions by the number of lakhs in a billion:
\[ 1,000,000,000 \div 100,000 = 10,000 \]
Thus,
\[ 1 \text{ billion} = 10,000 \text{ lakhs} \]

### Conclusion
From the calculations above, we can conclude that:
\[ 1 \text{ billion} = 1,000 \text{ million} = 10,000 \text{ lakhs} \]

### Answer
1 billion is equal to **10,000 lakhs**.
