Hi!

Let's set up a proportion to solve this.

(x)/(50) (30)/(100)

Cross multiply to solve for x.

50 * 30 = 1500
1500/100 = 15

The answer is 15 grams of cocoa.

Hope this helps! :)

Hello!

You have to find 30% of 50.

You can make a proportion. 30% = 30/100

(30)/(100) = (x)/(50)

Cross multiply

30 × 50 = 1,500

Divide by 100

1,500 ÷ 100 = 15

$\framebox {15 grams of cocoa}$
