Answer 2

25.62 grams of cocoa

Explanation:

To find the number of grams of cocoa in Keith's chocolate bar, we need to multiply the weight of the chocolate bar in grams by the percentage of cocoa in decimal form.

First, we convert the percentage to a decimal by dividing it by 100:

42% = 42/100 = 0.42

Next, we multiply the weight of the chocolate bar by the percentage of cocoa:

0.42 x 61 = 25.62

Therefore, the chocolate bar contains 25.62 grams of cocoa, rounded to the nearest tenth.
