Question

How do you round \[907.457\] to the nearest ten’s place?

Answer 1

Hint: In order to round off the given number, we first evaluate the number. Here we need to round it off to the nearest ten’s place, therefore we only see the whole number part. We take two numbers with the nearest ten’s digits and compare our given number with them. Thus, we find our required answer by rounding off our given number to the ten’s digit it is closest to.

Complete step-by-step solution:
The given number is: \[907.457\] . We need to round it off to the nearest ten’s place. As we have been asked to round off to the “tens place”, therefore we need not use the numbers after the decimal point, but if we were asked to round off to the nearest “tenth’s place”, then we would have considered the numbers after the decimal point. Now, in order to round off to the “tens place”. Let us consider two whole numbers closest to \[907.457\] , here the two whole numbers are $900$ and $910$ .
We find that \[907.457\] is closer to $910$ (the distance of only three numbers) while it is farther from $900$ (distance of seven numbers)

Hence we can round off \[907.457\]to the nearest ten’s place as : $910$

Note: We round off numbers to get an estimate of the nearest whole numbers and to make calculations easier. Rounding off numbers is quite useful in our day-to-day activities. For example, we are going out to buy groceries and we are to calculate the price of two things which cost, say Rs. $22.5$ and Rs. $3.99$ , then we can simply round off the numbers as Rs. $22$ and Rs. $4$, add them up and simply get our required sum.
