The following two-way table shows the data for the students of two different grades in a school: Member of School Band Not Member of School Band Total Grade 7 10 8 18 Grade 8 10 2 12 Total 20 10 30 Based on the relative row frequency, the students of which grade are more likely to be members of the school band? Grade 7 Grade 8 The students of both grades are equally likely to be members of the school band No conclusion can be drawn about the chances of a student being a member of the school band

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
