Answer:
4.48 = 5
12.96 = 13
123,987.93 = 123,988
Explanations:
To round each of the number to the nearest ones means to round them to the nearest unit. The unit is the digit preceding the decimal point.
4.48 = 5
8 is more than 5, it becomes 0 and add 1 to 4, we have 4.50 ( to 1 dp)
Then we approximate 4.50 to the nearest whole number, change 5 to 0, and add 1 to 4 to become 5.
The answer is 5 ( to the nearest one)
12.96 = 13 ( to the nearest one)
Change 6 to 0 and add 1 to 9, it becomes 10, carry the 1 in 10 to 12, it becomes 13.
123,987.93 = 123,988 (to the nearest one)
Since 9 is greater than 5, you make it zero and add 1 to 7. The number then becomes 123,988
