Here is the nutritional information for a 110g serving of cereal - OCR - GCSE Maths - Question 4 - 2018 - Paper 1

To determine if more than 90% of the serving is carbohydrates, we first need to calculate 90% of the total weight of the cereal serving. The total weight is 110g.

1. Calculate 90% of 110g: $90\\% \text{ of } 110g = 0.90 \times 110g = 99g$

2. Compare the amount of carbohydrates: The amount of carbohydrates in the cereal is 99.4g.

3. Now, since:

   • 99.4g (carbohydrates) > 99g (90% of total) it follows that Emily is correct because the amount of carbohydrates is greater than 90% of the total serving.
