Final answer:
To determine the fraction of students making either a video or a diorama, we add 1/2 and 1/12, resulting in 7/12 of the students engaging in one of these two projects.
Step-by-step explanation:
To find what fraction of the students are making either a video or a diorama for their final project in Kaylee's history class, we need to add the fractions of students doing each project. This involves adding 1/2 (students making videos) to 1/12 (students making dioramas).
First, we find a common denominator for the fractions, which is 12. The fraction 1/2 is equivalent to 6/12 when we multiply both the numerator and the denominator by 6. We do not need to change 1/12 because it already has the common denominator of 12.
Adding the two fractions together:
- 6/12 (videos) + 1/12 (dioramas) = 7/12
So, 7/12 of the students in the class are making either a video or a diorama for their final project.
