carmela cut a cake into 12 equal-sized pieces. She ate 2/12 of the cake and her brother ate 3/12 of the cake.What fraction of the cake
What is your question?
I think it is something like what fraction of the cake is left. In that case, it would be 3+2 = 5 and then 12- 5 = ?
To find the fraction of the cake that Carmen and her brother ate, you need to add the fractions together.
Carmela ate 2/12 of the cake, and her brother ate 3/12 of the cake.
To add these fractions, you need to have a common denominator. In this case, since both fractions have the same denominator of 12, you can simply add the numerators.
2/12 + 3/12 = 5/12
Therefore, Carmela and her brother ate a total of 5/12 of the cake.
