Question

Rafael's chocolate bar is 37% cocoa. If the weight of the chocolate bar is 96 grams, how may grams of cocoa does it contain? Round your answer to the nearest tenth.

Answer 1

You can use the weight of the chocolate bar given and find its 37% to get the weight of cocoa used in it.

The weight of cocoa in the given chocolate bar is 35.52 grams.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

Since weight of cocoa = 37% percent of chocolate bar's weight which is 96 gram,

Thus,

$weight$ $of$ $cocoa=\frac{37}{100}$ × $96=35.52$

Thus,

The weight of cocoa in the given chocolate bar is 35.52 grams.
