Round off 82 to its nearest tens

While rounding of a number to its nearest tens we focus on the digit at its ones place. Here the digit at the ones place is 2. 2 is nearest to 0 as compared to 10 Therefore, at ones place we will write 0 in place of 2 So the correct answer is 80 Alternatively, 82 is nearest to 80 as compared to 90, 100 or 0. So, it will be rounded off to 80.

If 9234 is rounded off to its nearest hundred and tens then the number will be _____ and _____ respectively

Solve the riddle “I am a three digit number I am an even number Round me off to the nearest hundred and I will be 300 I am one of the following numbers. Who am I? “

To solve riddle we need to check all the options 245 - It is a three digit number. 245 is an odd number. By rounding off 245 to nearest 100 we get 200 It is not the required number. 278 - It is a three digit number. 278 is an even number. By rounding off 278 to nearest 100 gives 300. Therefore the required three digit number is 278. Hence option 2 is correct answer 222 - It is a three digit number. 222 is even number By rounding off 222 to nearest 100 we get 200 Therefore, it is not the required number. 291 - It is a three digit number. By rounding off 291 to nearest 100 we get 300 but 291 is an odd number. Hence, it is not the required number.

Estimate the addition of 23512 and 4560 by rounding off each number to nearest 100

23512 rounded off to nearest 100 = 23500 4560 rounded off to nearest 100 = 4600 The estimated addition = 23500 + 4600 = 28,100 Hence option 4 is the correct answer. Some students don't read the question carefully and instead of rounding off the numbers to nearest 100, they round it off to nearest 10 and get the answer 28070 and choose option 1 which is an incorrect answer. Some round off the numbers to nearest 1000 and give option 2 as the answer whereas others just calculate and give option 3 as the answer.

Shruti walked 2374 steps on Monday, 3827 steps on Tuesday and 1187 on Wednesday. Estimate total number of steps walked by Shruti by rounding off the numbers to nearest thousands.

2374 rounded off to nearest thousands = 2000 3827 rounded off to nearest thousands = 4000 1187 rounded off to nearest thousands = 1000 So, estimated value of total number of steps = 2000 + 4000 + 1000 = 7000
