Answer:

It contains 55.5 grams of cocoa.

Step-by-step explanation:

This question can be solved using a rule of three.

The weight of the chocolate bar, which is of 91 grams, is 100% = 1. We have that it is 61% = 0.61 of cocoa. How many grams of cocoa are there?

91 grams - 1

x grams - 0.61

Applying cross multiplication

x = 91*0.61 = 55.5

It contains 55.5 grams of cocoa.
