Question

Sam made a cake and Gloria made some frosting to go on top of the cake Sam used 3/4 teaspoon of vanilla in the and Gloria used 1/3 teaspoon of vanilla in the frosting. How many teaspoons of vanilla were used in all

Answer 1

We have the following:

To calculate the total value used, we must use what each person used, as follows

`(3)/(4)+(1)/(3)=(3\cdot3+4\cdot1)/(4\cdot3)=(9+4)/(12)=(13)/(12)`

That is, in total 13/12 teaspoons of vanilla were used
