AI Solver by AskSia

Percentage Solver: every percent problem, solved

Type or photograph any percent question: what is 23% of 480, what percent of 75 is 18, 60 increased by 35%, a $89 jacket on 40% off, or 'after a 20% raise my salary is $54,000, what was it before.' AskSia identifies the type, converts the percent to decimal or fraction as needed, sets up the equation, and reports the answer with units.

Works with word problems, equations, code, and science prompts.

Quick Answer

How do you solve a percent problem?

Percent means 'per hundred,' so a percent is a fraction with denominator 100. To find a percent of a number, convert the percent to a decimal and multiply. To find what percent one number is of another, divide and convert to percent. For percent change, divide the difference by the original and convert. For reverse percent, set up an equation: if a value is the result of a percent change applied to the unknown, solve for the unknown. AskSia handles all four types.

Why AskSia Solver

Why students use AskSia for percentages.

Conversions, proportions, and word problems, all clear.

Every percent type covered.

Percent of, percent change, markup and discount, reverse percent. AskSia identifies which one you are asking and applies the right setup.

All types

Conversions shown.

23% becomes 0.23 or 23/100 explicitly. AskSia uses whichever form is computationally cleanest for your problem.

Transparent

Proportion option.

Many percent problems are easier as a/100 = part/whole. AskSia sets up the proportion and cross-multiplies when it helps.

Proportion

Word problem parsing.

Plain-English questions like 'a coat marked down by 30% costs $63, what was the original' get translated to equations and solved.

Word problems

Units preserved.

Dollars stay dollars, students stay students, percent stays percent. AskSia carries units through every step.

FAQ

Frequently asked questions.

How do you convert a percent to a decimal?
Move the decimal point two places to the left, which is the same as dividing by 100. So 23% becomes 0.23, 7% becomes 0.07, and 145% becomes 1.45. AskSia performs this conversion as an explicit step every time it uses a percent, so the relationship between the two forms stays clear.
What is the formula for percent change?
Percent change = (new value minus old value) divided by old value, then multiplied by 100 to express as a percent. If the new value is larger, the change is positive (a percent increase). If smaller, the change is negative (a percent decrease). AskSia uses this formula directly and labels the result as an increase or decrease.
How does reverse percent work?
When the result of a percent operation is known and you want the original, set up an equation. If a 20% discount gives a final price of $80, then $80 = 0.80 * original, so original = $80 / 0.80 = $100. AskSia identifies reverse-percent questions, writes the equation, and solves for the unknown.
Can AskSia handle compound percent like interest?
Yes. For compound percent (interest that earns interest, growth that compounds, etc.), AskSia applies the percent operation repeatedly: after n periods at rate r, the value is original * (1 + r)^n. For continuous compounding, it switches to original * e^(rt). The formula used appears alongside the arithmetic.
How accurate is AskSia?
AskSia is engineered for accuracy on standard high school and college coursework. Accuracy comes from subject-specialized models, a symbolic verification pass that catches arithmetic errors, and a self-check step that re-derives the answer before showing it to you.
Can I get practice problems and flashcards?
Yes. After any solve, ask Sia to generate similar practice problems at SAT, ACT, AP, IB, or college difficulty, or build a flashcard set on the underlying concept in one tap. Useful for exam prep and spaced repetition before a quiz, midterm, or final.
How much does AskSia cost?
AskSia has a free plan that includes daily solves across all subjects. AskSia Pro and Super include unlimited solves, advanced subjects, the full AI tutor companion, exports, and priority response speed. See pricing for details.
