The population of big cats in Africa is increasing at a rate of 5 % per year At the
beginning of 2004 the population was 10 000. (a) Write down the population of
big cats in Africa at the start of 2005. (b) Find the population of big cats at the
beginning of 2010. (c) Find the number of years, from the beginning of 2004. it
will take the population of big cats to exceed 50,000.

x=±√-4/225

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.
