A) 10%, increase
B) 20%, increase
C) 10%, decrease
D) 20%, decrease

Answer 1

To calculate the percent of change from 0.1 to 0.2, subtract the original from the new amount to find the change, divide this change by the original amount, and multiply by 100. This results in a 100% increase.

Step-by-step explanation:

To find the percent of change from 0.1 to 0.2, we need to follow these steps:

1. Identify the original amount (0.1) and the new amount (0.2).
2. Calculate the change in quantity, which is the new amount minus the original amount: 0.2 - 0.1 = 0.1.
3. Divide the change in quantity by the original quantity: 0.1 / 0.1 = 1.
4. Convert the result to a percentage by multiplying by 100: 1 × 100 = 100%.
5. Since the new amount is greater than the original amount, the percentage change is an increase.

Therefore, the correct option is C) 100%, increase.
