Question 2: Josie took a long multiple-choice, end-of-year vocabulary test. The ratio of the number of problems Josie got incorrect to the number of problems she got correct is 2: 9.

If Josie missed 8 questions, how many did she get correct? Draw a tape diagram to demonstrate how you found the answer.

If Josie missed 20 questions, how many did she get correct? Draw a tape diagram to demonstrate how you found the answer.

What ratios can we say are equivalent to 2 : 9?
