Write, interpret, and compare ratios using words, symbols, tables, and diagrams.
Write a ratio from words
Problem
A bag has \(5\) red marbles and \(8\) blue marbles. Write the ratio of red marbles to blue marbles in \(a:b\) form.
Big Picture
What this problem is really about
A ratio preserves the order of the quantities named, so red must occupy the first position and blue the second. We’ll match each marble count to that order and write the comparison in colon form. Reading the completed ratio back in words checks that neither term was reversed or replaced by the total.
