Wilson has 60 chocolates. he gives 30% of the chocolates to kids. write the number of chocolates that he gave to kids

You have to set up proportions or two fractions equal to each other. x will be equal to a number of chocolates Will gives to the kids.
 
Cross multiply and they you'll get 1800 = 100x
Divide both sides by 100 and you get x = 18
Therefore Will gives 18 chocolates to the kids

The answer would be the second choice : )
