Recently, while working on some math homework, Carmen and Mario got into a little argument. During the dispute, a part of their assignment was destroyed. All that remained of one
particular problem is shown below.

Carmen was furious. “Way to go, Mario! Now there is no way to get this problem correct! We don't
even know what f(x) is.”
“Wait a minute!” Mario quickly responded. “I’m pretty sure we can solve this anyway.”
Carmen shook her head.
Who is correct? Explain completely why and what the other person might be forgetting.

Step-by-step explanation:

are you an artist's daughter? cuz dang you a fine piece of art, girl.

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.
