Answer:
5.670 rounded to the nearest whole gram is 6 grams.
Explanation:
This is because when rounding if the digit in the tenths column is a number greater than or equal to 5 you would round up. However if the number is less than 5 you would round down.
Example:
1) Round 13 to the nearest 10.
In this case you would round down as the digit in the units column is less than 5.
2) Round 19 to the nearest 10.
In this case you would round up to 20 as the digit in the units column is greater than 5.
