sophie ruth is eating a chocolate bar that is 50 grams and 30%coca how many grams of coca are in the bar

15 grams of cocoa are in the bar

Step-by-step explanation:

So, to solve this, we are trying to find 30% of 50 grams

when we hear the word OF that means we need to multiply.

So, our equation is now

30% x 50

To make this problem a bit easier, we should convert 30% into a decimal

30% as a decimal is 0.30, or simply 0.3

That means, our new equation is

0.3 x 50

and, 0.3 x 50 equals,

15 grams of cocoa in the bar
