In a bag there are 2 red buttons 3 green buttons, and 4 purple buttons A student writes the ratio for the number purple buttons to green buttons as 3:4 is the student correct explain why or why not.
No, the student is not correct. The ratio of purple buttons to green buttons should be 4:3, not 3:4. This is because there are 4 purple buttons and 3 green buttons. The number corresponding to the purple buttons should come first in the ratio because it was listed first in the comparison. Therefore, the ratio listing the purple buttons first should have the number corresponding to the count of purple buttons first, which is 4, not 3.
No, the student is not correct. A ratio compares two quantities. In this case, the student is comparing the number of purple buttons to the number of green buttons. However, the ratio should be written as the number of purple buttons to the number of green buttons.
According to the information provided, there are 3 purple buttons and 3 green buttons. Therefore, the correct ratio for the number of purple buttons to the number of green buttons is 3:3, which simplifies to 1:1.
To determine if the student's ratio is correct, we need to compare the actual number of purple buttons to the number of green buttons.
According to the given information, there are 2 red buttons, 3 green buttons, and 4 purple buttons in the bag.
Let's calculate the ratio of purple buttons to green buttons:
Number of purple buttons: 4
Number of green buttons: 3
The ratio can be written as 4:3, not 3:4.
Therefore, the student's ratio is incorrect. The correct ratio for the number of purple buttons to green buttons is 4:3.
