Eric's chocolate bar is 56% cocoa. If the weight of the chocolate bar is 78 grams, how many grams of cocoa does it contain? Roun
alexgriva [62]

Answer:

The answer to your question is 43.7 g of chocolate

Step-by-step explanation:

Data

56% cocoa

mass of a chocolate bar = 78 g

Process

To solve this problem, use proportions and cross multiplication, consider the mass of the bar is 100%.

                          78 g of chocolate ------------------- 100%

                             x                          ------------------    56%

                                            x = (56 x 78) / 100

                                            x = 4368/100

                                            x = 43.68 g

-Round to the nearest tenth

             Mass of the chocolate = 43.7 g

Which of the following
Archy [21]

The answer you are looking for is 36.

If you line up the numbers numerically (4, 8, 16, 32, 36, 64), you'll see that there's a pattern. Each number, multiplied by 2, gets the next number in the sequence. 4 * 2 = 8, 8 * 2 = 16, 16 * 2 = 32, and 32 * 2 = 64.

Thus meaning 36 is the odd number out. I hope this helps!
