In a bag there are 2 red buttons, 3 green buttons, and 4 purple buttons. A student writes the ratio for the number of purple buttons to green buttons as 3:4. Is this student correct? Explain why or why not
1 answer
No, the student is not correct. To write a ratio, we need to compare two quantities. The student compares the number of purple buttons to the number of green buttons and writes the ratio as 3:4, meaning there are 3 purple buttons for every 4 green buttons. However, there are actually 4 purple buttons and 3 green buttons. Therefore, the correct ratio for the number of purple buttons to green buttons is 4:3.
