Question

in a bag there are two red buttons, three green buttons and four purple buttons a student writes the ratio of number of purple buttons to green buttons is 3 to 4. Is this student correct? Explain why or why not? Explain in 2 to 3 sentences.

Answer 1

The student's ratio of purple buttons to green buttons as 3 to 4 is incorrect. There are 4 purple buttons and 3 green buttons in the bag, which gives a ratio of 4 to 3, not 3 to 4. Thus, the correct ratio should be written as 4:3.
