Question

What is $ 6050.287 $ rounded to the nearest tenths?
A. $ 6050 $
B. $ 6100 $
C. $ 6050.29 $
D. $ 6050.3 $

Answer 1

Hint: Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. The most common method to round is as follows:
Step 1. Choose which is the last digit to keep.
Step 2. Leave it the same if the next digit is less than 5.
Step 3. Increase it by 1 if the next digit is 5 or more.

Complete step-by-step answer:
We are asked to round $ 6050.287 $ to the nearest tenth place, which means that round the number till there is one digit after the decimal point. We will do this by rounding the digits one after another.
The last digit to keep in $ 6050.287 $ is $ 8 $ , as the digit next to it is $ 7 $ which is greater than $ 5 $ . We have to increase it by $ 1 $ to remove $ 7 $ . So, after rounding once
 $ 6050.287 $ can be written as $ 6050.29 $ . To reach the nearest tenth place, we have to round it once more. Now, the last digit to keep is $ 2 $ , as the digit next to it is $ 9 $ which is greater than $ 5 $ . We have to increase 1 again to remove 9. So, after rounding $ 6050.29 $ can be written as $ 6050.3 $ .
By rounding to the nearest tenth place $ 6050.287 $ can be written as $ 6050.3 $ .
So, option (D) is the correct answer.
So, the correct answer is “Option D”.

Note: In this question we rounded the digits which were after decimal. But we can also round the integers similarly. For example:
64 can be rounded as 60, 52 can be rounded as 50, 89 can be rounded as 90.
