Question

1. from 284 grams to 206 grams

Explanation:

Step1: Find the change in value

To find the change, subtract the final value from the initial value. So, \( 284 - 206 = 78 \) grams.

Step2: Calculate the percent change

The formula for percent change is \( \frac{\text{Change in Value}}{\text{Initial Value}} \times 100\% \). Substituting the values, we get \( \frac{78}{284} \times 100\% \approx 27.46\% \) (decrease, since the value went down).

Answer:

The percent change is approximately a \( 27.46\% \) decrease (or if just the amount of change is asked, it's a decrease of 78 grams; depending on the context, but likely percent change here, so approximately \( -27.46\% \) or a \( 27.46\% \) decrease). If we consider the absolute change in mass, it's 78 grams decrease. If percent change:

First, change in mass: \( 206 - 284=- 78 \) grams.

Percent change: \( \frac{-78}{284}\times100\%\approx - 27.46\% \), which means a \( 27.46\% \) decrease.
