Question 5.
Round 4.75 to the nearest whole number.
Answer:
4.75 is rounded to the nearest whole number as 5.
Explanation:
If the first digit after decimal point is less than 5 then we have to remove the numbers after decimal point.
If the first digit after decimal point is greater than or equal to 5, then we have to add 1 to the number before decimal point and remove all the numbers after decimal point.
The first digit after decimal point is 7 which is greater than 5. So, add the number 1 to the before decimal point number 4.
So, 4.75 is rounded to the nearest whole number as 5.
