Question

8. List all the numbers which can be rounded off to 40​

Answer 1

Answer:

36 37 38 39 40 41 42 43 44

Step-by-step explaination:

1. Rounding of numbers done by rounding them to nearest ten(nearest number which has zero in it's one's place).

2. For example take 34 which is rounded to 30.

3. Numbers having 0 1 2 3 4 numbers in one's place will be rounded to preceding number (which has zero in it's one's place). Just like the example in 2nd point. and numbers with 5 6 7 8 9 numbers in one's place are rounded to succeeding number (which has zero in one's place).

*4. But rounding 5 in one's place is little tricky one. If the number with 5 in one's place is right side of the rounding number then + 1 is added to 5. if not -1. Just like not including 45 when rounding to 40 in above question.
