Final answer:
A watermelon is about 80% water. Then about 20 grams of the watermelon are not water
The correct answer is option 1
Step-by-step explanation:
To find out how many grams of a watermelon are not water, we need to consider that the watermelon is about 80% water. This means that 80% of the total weight of the watermelon is water.
Let's assume the total weight of the watermelon is 100 grams for simplicity. To calculate the weight of water, we can multiply the total weight (100 grams) by the percentage of water (80%):
Weight of water = 100 grams * 80% = 80 grams
Now, to find the weight of the watermelon that is not water, we can subtract the weight of water from the total weight of the watermelon:
- Weight of watermelon not water = Total weight - Weight of water
- Weight of watermelon not water = 100 grams - 80 grams = 20 grams
Therefore, approximately 20 grams of the watermelon are not water.
The correct answer is option 1) 20 grams, as it matches the calculated value.
