Question

How do you round \[34\] to the nearest hundred?

Answer 1

Hint: Here in the above question we are asked to round \[34\] to the nearest hundred. While rounding the number to the nearest hundred we will look at the digit and we will round up the number to the nearest hundred if the last two digits in the number are \[50\] or above while we will round the number down to the nearest hundred if the last two digits in the number are \[49\] or below. Lastly if the last two digits are \[00\] then no rounding is required as it is already to the hundred.
If the last two digits of numbers are \[50\] or above so we will round the number up to the nearest hundred while if the last two digits of the number are \[49\] or below we will round the number down to the nearest hundred.

Complete step by step solution:
In the above question we have to round \[34\] to the nearest hundred. So now we will check the last two digits of the number which is \[34\]
As we know that if the last two digits in the number are \[49\] or below then we will round the number down to the nearest hundred. Now as we can see that \[34\] is less than \[50\]
Therefore we will round the number down to the nearest hundred.
Hence the given number \[34\] is rounded to the nearest hundred is \[0\]
So the answer is \[0\]
So, the correct answer is “0”.

Note: As we can see that while solving the above question rounding is done which means to replace a number with a simpler value. It is basically a process of estimation. Remember it is done for making calculations easier and convenient to use while talking about big numbers. Keep in mind that rounding off is not useful when we deal with precise quantities and numbers as it gets deviated from the original number. Like, while rounding off the numbers with decimal digits, the number of significant digits decreases leading to the reduction in accuracy. Make sure that the last two digits are deciding one so check carefully.
