Percentages

What really happens to a price after a discount and then tax? These SAT Problem Solving and Data Analysis quizzes on percentages build the fluency to chain those calculations without slipping.

Percentage Calculations That Build on Each Other

You will strengthen the fundamentals of finding the part, the whole, or the percent in everyday scenarios, then take on multi-layered problems with successive changes, discounts combined with tax, and questions that ask you to work backward to an original value. A $50 item at 20 percent off drops to $40, and from there the quizzes stack on extra steps that trip up anyone working too fast.

Percentages run through real life, from tips and sales to interest and statistics, so this is one of the most useful math skills the SAT tests. The challenge is rarely a single calculation; it is keeping track of what each percent applies to. That single idea, watching the base that each percent is taken from, is what separates a quick correct answer from a confident wrong one. Slow down on the base, and the rest of the arithmetic usually falls into place.

Did You Know?

A 20 percent increase followed by a 20 percent decrease does not return you to where you started. Beginning at 100, the increase takes you to 120, and then a 20 percent cut drops you to 96. Each percent applies to a different base, which is exactly why these stacked changes catch people off guard.

How the Quizzes Work

Three quizzes climb from clean single-step percent problems to layered ones that demand careful tracking. Each takes only a few minutes, so steady practice fits around everything else. Repeating them makes the multi-step problems feel far less intimidating.
