d. 30.


Sagot :

Answer:

The amount of chocolates Marina was left with after the split was 12. Therefore the correct answer is a. 12.

Step-by-step explanation:

According to the wording of the question, Marina and Rafaela bought 30 chocolates and that this amount would be divided proportionally to the number of children of each one. In this case, Marina has 2 children and Rafaela has 3 children, so:

2 + 3 = 5

The fraction representing the amount of chocolates that each one should receive will be given by the ratio between the number of children and the total number of children added together, so:

Marina: 2/5

Rafaela: 3/5

Thus, the amount of chocolates that Marina should receive is given by:

2/5 x 30 = 12 chocolates
