Here we have to apply the method of place value.
Place value is the numerical value that a digit has by virtue of its position in a number.
Let us find place value of 3 in each number.
In 47,235, 3 is in tens place, so its place value is 30.
In 2,438,017, 3 is in ten thousands place , so its place value is 30,000.
Now we have to find how many times as the value of digit 3 in 47,235 (30) is value of the digit 3 in 2,438,017 (30,000)
so comparing 30 and 30,000,
we can say that 30 is 1000 times 30,000
or we can say value of digit 3 in 47,235 is 1000 times value of the digit 3 in 2,438,017.
