Free SAT Ratios, rates, proportional relationships, and units Practice Questions
The SAT tests ratios, rates and units through proportional reasoning problems: scaling recipes, comparing speeds, converting between units. Setting the proportion up correctly is the entire question; the arithmetic is deliberately easy.

Preparing the question set…
Try three questions before signing in. Your first miss opens a hint; the full solution stays sealed until you solve or reveal it.
How the SAT tests ratios, rates, proportional relationships, and units
You set up and solve proportions, work with part-to-part versus part-to-whole ratios, and convert units including squared and cubed ones.
Where the points go
Inverting the proportion, and forgetting that converting an area squares the conversion factor.
Every question you miss here is added to your mistake log with the specific error identified, and brought back after three days and again after fourteen — no screenshots, no error journal to keep.
