Question

1. from 309 grams to 299 grams

Explanation:

Assuming the problem is to find the percent decrease from 309 grams to 299 grams.

Step1: Find the amount of decrease

First, we calculate the difference between the original amount and the new amount. The formula for the amount of decrease is \( \text{Decrease} = \text{Original Amount} - \text{New Amount} \).
So, \( 309 - 299 = 10 \) grams.

Step2: Calculate the percent decrease

The formula for percent decrease is \( \text{Percent Decrease} = \frac{\text{Decrease}}{\text{Original Amount}} \times 100\% \).
Substituting the values we have, \( \text{Percent Decrease} = \frac{10}{309} \times 100\% \approx 3.24\% \) (rounded to two decimal places).

Answer:

The percent decrease from 309 grams to 299 grams is approximately \( 3.24\% \).
