Final answer:
Sandy used 4 sheets to make posters, leaving her with 2 sheets of paper. Each sheet can be cut into 4 rectangles, so she can make 8 greeting cards in total.
Step-by-step explanation:
The question involves Sandy who has 6 sheets of colored paper and uses 4 to make posters. This leaves her with 2 sheets. She then cuts the remaining paper into rectangles, each being 1/4 of a sheet. To find the number of greeting cards she can make, we calculate the number of quarters in 2 sheets of paper:
- Each sheet can be cut into 4 rectangles because each rectangle is 1/4 of a sheet.
- Therefore, 2 sheets can be cut into 2 x 4 = 8 rectangles.
Hence, Sandy can make 8 greeting cards from the 2 remaining sheets of colored paper.
