Answer:
gram
Step-by-step explanation:
The 2nd number position after the decimal is always the hundredth position, so we will work from there. To round a number, you must examine the number that comes after the number you are trying to round. In this case the number you are trying to round is the 8 so we have to look at the 2. because the two is a number less than 5, the 8 will remain an 8 and your rounded answer is 4.08. If that two had been a number greater than 5 than the 8 would have become a 9 and your answer would have been 4.09. When rounding always remember: "5 to 9, up the line; 0 to 4, down to the floor."
