Question

Andrea and her partner are writing a 12-page science report. They completed 25% of the report in class and 50% of the remaining pages after school. How many pages do Andrea and her partner still have to write?

Answer 1

Andrea and her partner still have 4.5 pages to write.

Step-by-step explanation:

To find out how many pages Andrea and her partner still have to write, we need to first determine the number of pages they completed in class and the number of pages they completed after school.

1. In class, they completed 25% of the report. 25% of 12 is 3 pages, so they completed 3 pages in class.
2. They still have 12 - 3 = 9 pages remaining.
3. After school, they completed 50% of the remaining pages. 50% of 9 is 4.5, so they completed 4.5 pages.

Therefore, Andrea and her partner still have 9 - 4.5 = 4.5 pages to write.
