Question

Round off to the nearest one (ones place)÷
1.) 9.909
​

Answer 1

Answer:

10

Step-by-step explanation:

The numbers from 0 to four are rounded off to the lower number ad the numbers from 5 to 9 are rounded to the higher number. It is decided by looking at the number before the number before the number we are focusing on. For example,

98 is rounded off to 100 as 98 is closer to 100 than it is to 90

99.8 is rounded off to 100 as it is 0.2 less than 100.

In the question asked, the number is 9.909. For all numbers start from the right side and come towards the left. The 9 in the 3rd decimal place is rounded off to 9.910 as 9.909 is closer to 9.910. Then 1 is rounded off to 9 as the 9.91 is closer to 9.90 . So then all we have to consider the number 9.9 . As 9.9 is just 0.1 less than 10, we round it off to 10
