Scaling guides

Scale any recipe,
by the right ratio.

Four step-by-step guides for the most-asked scaling ratios. Each guide has the worked math, the salt-and-spice corrections that linear multipliers miss, and the cases where the recipe shouldn't scale at all. Or skip the math and use the scaler directly.
