Comparing Ratios Using Ratio Tables and Percents

The video tutorial teaches how to compare quiz results using ratio tables and percents. It begins by introducing a problem involving Susan's quiz scores in history and science. The tutorial reviews the use of ratio tables with addition and multiplication, and explains the concept of percents as a part-to-total ratio. It then analyzes Susan's quiz results, highlighting the importance of considering total questions when comparing scores. By converting ratios to percents, the tutorial demonstrates how to make accurate comparisons, concluding that Susan performed better on her science quiz.

What is the primary purpose of using ratio tables in solving ratio problems?

• To focus only on the number of correct answers

• To organize and simplify the comparison of ratios

• To add complexity to the problem

• To eliminate the need for percents

Why is it incorrect to compare Susan's quiz performances based solely on the number of correct answers?

• Because the quizzes were taken on different days

• Because Susan guessed some answers

• Because the total number of questions in each quiz was different

• Because the quizzes were on different subjects

How can ratio tables help in comparing Susan's quiz performances?

• By converting the ratios into a common total for comparison

• By organizing the data into a visual format

• By highlighting the subject matter of each quiz

• By showing the number of incorrect answers

What is the advantage of using percents to compare quiz performances?

• Percents are easier to calculate

• Percents allow for comparison with a common total

• Percents eliminate the need for ratio tables

• Percents focus on incorrect answers

How is comparing ratios similar to comparing fractions?

• Both require finding a common numerator

• Both involve converting to a common total or denominator

• Both focus on the number of correct answers

• Both are used only in math quizzes
