SAT Ratios, Rates, and Proportions Worksheet

What this worksheet covers

Ratios, Rates, and Proportions belongs to the Problem-Solving and Data Analysis domain on the Digital SAT Math section.

Use this as a one-skill worksheet before timed modules. The goal is not just to get questions right, but to recognize the pattern quickly under SAT timing.

• Official skill: Ratios, rates, proportional relationships, and units
• Section: Math
• Domain: Problem-Solving and Data Analysis
• Best use: focused drill session before a timed module

Rules to remember

Before drilling this skill, memorize the core rules below and keep them next to your scratch work.

• Write units beside every number — cancel units like variables.
• Cross-multiply only after you've verified the two ratios compare the same quantities.
• For percent change, use (new − old) / old × 100.

Practice routine

Start untimed until you can explain the pattern. Then switch to timed sets so the skill holds up inside a full module.

• Do 10 warmup questions and write down every mistake type.
• Do 20 timed questions from the same skill.
• Review missed questions without looking at the explanation first.
• Repeat the misses 48 hours later to confirm the fix stuck.

How to use this on real SAT questions

Ratios, Rates, and Proportions questions are easiest to improve when you practice the recognition step before the calculation step. First identify the Problem-Solving and Data Analysis pattern, then choose the fastest method.

Inside the bank, start untimed until you can explain why the answer works. Then rerun the same skill under time pressure and review only the misses and guesses.

• Write units beside every number — cancel units like variables.
• Cross-multiply only after you've verified the two ratios compare the same quantities.
• For percent change, use (new − old) / old × 100.

How to recognize this question type

Ratios, Rates, and Proportions questions usually signal themselves through the representation they give you: an equation, table, graph, short passage, or answer-choice pattern tied to Problem-Solving and Data Analysis. Do not start calculating until you have named the pattern.

On a real module, the fastest students first decide whether the question is asking for a value, a relationship, an interpretation, or a rewritten form. That decision tells you which tool to use.

• Look for wording connected to Ratios, rates, proportional relationships, and units.
• Identify whether the answer should be a number, expression, sentence, or interpretation.
• Underline the exact value or claim the question asks for before touching the answer choices.
• Write units beside every number — cancel units like variables.
• Cross-multiply only after you've verified the two ratios compare the same quantities.
