Answer:
3 grams
Step-by-step explanation:
Whole numbers do not include any decimals. They include numbers such as 1, 2, 3, 4, 5...
2.500 g is equal to 2 and a half grams, which we know is between 2 and 3 grams. This means that the nearest whole gram has to be 2 or 3.
When rounding, look at the digit to the right of the digit being rounded, and if it is 5 or more, round up. If it is 4 or less keep the digit same.
Here, 5 is the digit to the right of 2, so we round up to 3 grams.
