Write an ordered list of five numbers whose values are between 50.98 and 51.6. tell whether your list is from least to greatest or greatest to least.

One possible answer is:

51.0, 51.1, 51.2, 5.13, and 51.4; the list is from least to greatest.

Explanation:

51.0 can be written as 51.00.  Comparing this to 50.98, we can see that 51.00 is larger.

51.1 is larger than 51.0; 51.2 is larger than 51.1; 51.3 is larger than 51.2; and 51.4 is larger than 51.3.  All of these numbers are also smaller than 51.6.

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.
