Question

How many millions make a billion?

Answer 1

Hint: Here, we need to convert 1 billion into million. We can do that by using the fact that 1 billion is equal to 1,000,000,000 and 1 million is equal to 1,000,000 and simple calculation. Simply multiply million amounts or value to 1000 to get the value of 1 billion in million.

Complete step-by-step answer:
Here, we will convert 1 billion into millions.
We know the fact that 1 billion is equal to 1,000,000,000 and 1 million is equal to 1,000,000.
Since we need 1 billion value thus we will multiply 1000 in equation of 1 million that is $1{\text{ million}} = 1000000$ to get the value,
$1{\text{ million}} \times 1000 = 1000000 \times 1000$
Now we will simplify both sides to get the value of 1 billion as,
$1000{\text{ million}} = 1000000000$
Since $1{\text{ billion}} = 1000000000$ and $1000{\text{ million}} = 1000000000$, we can say that ${\text{1 billion}} = 1000{\text{ million}}$.
Therefore, we can say that 1000 million will make 1 billion.

Note: We can also solve this question by using relation ${\text{1 billion}} = 1000{\text{ million}}$ directly. In this relation 1 will be multiplied in both sides to get the value of 1 billion in million as the billion term is 1. There is one more direct relation ${\text{1 million}} = 0.001{\text{ billion}}$which we can use to get the required answer for this question. In this relation 1000 will be multiplied to get the value of 1 billion .Here we multiplied 1000 in relation ${\text{1 million}} = 0.001{\text{ billion}}$. Since the billion term is $0.001$ which needs to convert into 1, we need to multiply it by 1000 to get the value of 1 billion. Using both the relations we will get the same answer that is 1000 million will make 1 billion.
