Question

Ravi’s chocolate bar is 62% cocoa. if the weight of the chocolate bar is 61 grams, how many grams of cocoa does it contain? Round your answer to the nearest tenth.

Answer 1

Recall that the x% of y can be computed using the following expression:

`y\cdot(x)/(100)\text{.}`

Now, since Ravi's chocolate bar is 62% cocoa, and the weight of the chocolate bar is 61 gr, then the chocolate bar contains:

`61\cdot(62)/(100)`

grams of cocoa.

Simplifying the above result we get:

`61\cdot0.62=37.82\approx37.8.`

Answer: Ravi's chocolate bar contains 37.8 grams.
