Answer 1

To find the number of grams of cocoa in Juan's chocolate bar, multiply the weight of the bar by the percentage of cocoa it contains. In this case, the chocolate bar contains 20.52 grams of cocoa.

Step-by-step explanation:

To find the number of grams of cocoa in Juan's chocolate bar, we need to multiply the weight of the bar by the percentage of cocoa it contains.

First, convert the percentage to a decimal by dividing it by 100: 38% = 0.38

Next, multiply the weight of the bar (54 grams) by the decimal representation of the cocoa percentage: 54 grams * 0.38 = 20.52 grams

Therefore, the chocolate bar contains 20.52 grams of cocoa.
