Q. Sophie Ruth is eating a

50

-gram chocolate bar which contains

30 \%

cocoa. How many grams of cocoa are in the chocolate bar?

Identify Whole and Percent: Identify the Whole and the Percent in the given problem. $\newline$ The whole is the total weight of the chocolate bar, which is $50$ grams. The percent is the cocoa content in the chocolate bar, which is $30\%$ .
Convert to Decimal: Convert the percent to a decimal to use in calculations. $\newline$ To convert a percentage to a decimal, divide by $100$ . So, $30\%$ becomes $0.30$ . $\newline$ Calculation: $30\% / 100 = 0.30$
Calculate Part: Calculate the Part, which is the amount of cocoa in the chocolate bar. $\newline$ Using the formula: $\text{Percent (as a decimal)} \times \text{Whole} = \text{Part}$ , we can find the amount of cocoa. $\newline$ Calculation: $0.30 \times 50$ grams = $15$ grams
Verify Calculation: Verify the calculation to ensure there are no math errors. $\newline$ Re-calculation: $0.30 \times 50$ grams = $15$ grams $\newline$ The calculation is correct and matches the previous result.
