The rule, 4 worked examples, and the mistake everyone makes.

- 3 : 5 · 3 to 5 · 3/5
- 3 red, 5 blue = part : part = 3 : 5
- 3 red out of 8 = part : whole = 3 : 8
- 6 : 10 = simplifies to 3 : 5
- 3 : 5 scaled up = 6 : 10, 9 : 15
- Common mistake: 3 red and 5 blue means 3/5 are red → 3/8 are red
A ratio is not a fraction unless it compares a part with the whole. Check which one the question means.

- Who is the Ratios poster for?
- Ratios is filed under 6th Grade (ages 11–12), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Ratios poster?
- Always ask which two things are being compared before writing anything down. A wall chart earns its place by being glanceable from where the work is happening, so Ratios belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Ratios?
- Absolute Value, Adding Integers and Algebra Vocabulary sit alongside Ratios in the 6th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Absolute ValueAdding IntegersAlgebra Vocabulary
- Is the Ratios poster free to download and print?
- Yes. Ratios downloads as a free PDF with no account, no email and no watermark, like everything else in the 6th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Ratios poster print at?
- Ratios is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Ratios loses nothing.Printing guide
