Answer :

To find the mass of one spoonful of sugar to the nearest gram, follow these steps:

1. Identify the given mass: We have been given that the mass of one spoonful of sugar is 9.75 grams.

2. Understand the concept of rounding to the nearest gram:
- If the decimal part of the number is 0.5 or higher, we round up.
- If the decimal part of the number is less than 0.5, we round down.

3. Analyze the decimal part: In the mass 9.75 grams, the decimal part is 0.75.

4. Determine the appropriate rounding action:
- Since 0.75 is greater than 0.5, we round up the whole number.

5. Perform the rounding:
- When we round 9.75 up, we get 10.

Thus, the mass of one spoonful of sugar, to the nearest gram, is 10 grams.
