Simple & Advanced fraction math with step-by-step solutions

History
No calculations yet.

Simple mode covers everyday fraction math: add, subtract, multiply, divide, simplify to lowest terms, compare two fractions, and convert between fraction, decimal and percent.

Advanced mode adds a full expression evaluator (type things like 1/2 + 3/4 × (2/3 − 1/5)) with a step-by-step breakdown, a mixed-number ↔ improper-fraction toolkit, and a "fraction of a quantity" / ratio & proportion solver.

From a quick “what’s 1/2 plus 3/4” to a full multi-operation expression with parentheses, this calculator handles fraction math at both a everyday level and an advanced level, with step-by-step solutions for the more complex cases.

How to use this fractions calculator

  1. Choose Simple mode for everyday operations, or Advanced mode for expressions and word problems.
  2. In Simple mode, pick a sub-tab: Operate, Simplify, Compare, or Convert.
  3. In Advanced mode, pick Expression (full formula evaluator), Mixed ↔ Improper, or Of a Quantity/Ratio.
  4. Enter your fraction(s) and read the Answer, Decimal, and Percent equivalents, plus a step-by-step breakdown where available.

What Simple mode covers

Simple mode handles the everyday fraction operations most people need: adding, subtracting, multiplying, and dividing two fractions or mixed numbers; simplifying a fraction to its lowest terms; comparing two fractions to see which is larger; and converting freely between fraction, decimal, and percent representations.

What Advanced mode adds

Advanced mode includes a full expression evaluator that accepts complex formulas like 1/2 + 3/4 × (2/3 − 1/5), complete with a step-by-step breakdown showing exactly how the answer was reached, respecting standard order of operations. It also includes a mixed-number to improper-fraction toolkit (and the reverse), and a solver for “fraction of a quantity” problems (like 3/4 of 120) as well as ratio and proportion problems (like solving for x in 2/5 = x/40).

Fraction of a Quantity: Result = (Numerator ÷ Denominator) × Quantity
Ratio & Proportion: solve for the unknown value that keeps both sides of a/b = c/d equal

Why step-by-step solutions matter

For anything beyond a single simple operation, seeing each intermediate step, finding a common denominator, simplifying along the way, applying order of operations, makes the difference between just getting an answer and actually understanding how it was reached, which is why the Expression mode includes a full breakdown rather than just a final number.

Frequently asked questions

Can this calculator handle a full expression with multiple operations?

Yes, Advanced mode’s Expression tab accepts a complete formula with fractions, mixed numbers, parentheses, and the four basic operations, following standard order of operations, and shows a step-by-step breakdown of how the answer was reached.

How do I solve a ratio problem like 2/5 = x/40?

Use the Ratio & Proportion tool under Advanced mode’s “Of a Quantity/Ratio” section, enter the known values and place “x” in the one unknown position, the calculator solves for it directly.

Can I convert a decimal back into a fraction?

Yes, the Convert tab in Simple mode supports both directions, fraction to decimal/percent, and decimal back to fraction.
