Question

the tape diagram shows that rita answered 14 questions correctly on a post - test. rita learned a lot in this unit, so that was 350% as many questions as she answered correctly in the pre - test. complete the table to show different percentages of the questions rita answered correctly on the pre - test. number of questions correct percentage 350% of the correct pre - test questions 50% of the correct pre - test questions 100% of the correct pre - test questions

Explanation:

Step1: Find pre - test correct questions

Let \( x \) be the number of correct pre - test questions. We know that \( 350\% \) of \( x \) is 14. Mathematically, \( 3.5x = 14 \) (since \( 350\%=3.5\)). Solving for \( x \), we divide both sides by 3.5: \( x=\frac{14}{3.5}=4 \).

Step2: Calculate 50% of pre - test correct

50% of \( x \) (where \( x = 4 \)) is \( 0.5\times4 = 2 \).

Step3: 100% of pre - test correct

100% of \( x \) (where \( x = 4 \)) is \( 1\times4=4 \).

Answer:

For "350% of the correct pre - test questions": 14
For "50% of the correct pre - test questions": 2
For "100% of the correct pre - test questions": 4
