Question

What is the place value of $7$ in the number of $710,621,684$
A. $700,000,000$
B. $7$ million
C. $7$ tens
D. $7$

Answer 1

Hint: Natural numbers are a part of the number system including all the positive integers from 1 to infinity. The value of each digit in a number is called its place value. Place value is the value of each digit in a number. For example, the $3$ in $350$ represents $3$ hundred or $300$ .We have to find the place value of $7$ in $710,621,684$ . So, we will try to expand it as position wise then we will find place value of

Complete step by step solution:
We have to find the place value of $7$ in $710,621,684$ .
So, we are going to expand it as per place value.
So, going from the left and taking it as the one th position and moving toward the right the place value is going to increase.
As 4 is in one place, hence we can write it as $4 \times 1$ here 1 defines its place value.
When we go toward the right. We can write 8 as $8 \times 10$ here 10 defines the place value which is at tenth position.
We can write $710,621,684$
$7 \times 100,000,000 + 1 \times 10,000,000 + 0 \times 1000,000 + 6 \times 100,000 + 2 \times 10000 + 1 \times 1000 + 6 \times 100 + 8 \times 10 + 4 \times 1$As we have to find the place value of 7. From above we find the place value for it to be 100000000.
Hence, the place value of $7$ is $700,000,000$

So, the correct answer is “Option A”.

Note: Natural numbers, also known as non-negative integers. 0 is NOT a natural number because natural numbers are counting numbers. Every natural number is a whole number. The whole numbers are the part of the number system in which it includes all the positive integers from 0 to infinity. These numbers exist in the number line.
