1. Type the whole number, a space, then the fraction
Mixed numbers read as 2 1/4 — whole first, one space, then numerator/denominator. The calculator also accepts improper entries like 9/4 and plain wholes like 2.

Make the parts match, regroup one whole when you need more pieces, then take away the second amount.

Notice the part sizes
The fractions name different-sized pieces, so they are not ready to subtract yet.

CapabilityHow it worksExample
Add and subtract mixed numbersEnter two mixed numbers — or mixed with fractions and wholes — and watch the regrouping happen bar by bar.2 1/4 − 1 2/3 = 7/12
Convert to improper fractionsThe multiply-add-keep formula turns 2 3/4 into 11/4 and back, with the remainder shown.2 3/4 = 11/4
Convert to decimalsAny mixed number reads as a decimal: the fraction part divides out, 3/4 = 0.75.2 3/4 = 2.75
Compare mixed numbersSame denominators or not, see which mixed number sits further along the number line.2 1/2 > 2 1/3
How to enter a problem
Four steps: type, operate, read, convert
2. Pick the operation and the second number
Use − for subtraction, + for addition, × and ÷ where the guides support them. This page’s tool focuses on the subtraction case, which needs regrouping most often.
3. Read the simplified answer
Results finish in lowest terms, with improper fractions regrouped into mixed numbers: 2 1/4 − 1 2/3 gives 7/12, and 1 1/2 − 1/2 gives the whole number 1.
4. Convert the answer if the question asks
The converters below turn any answer into its improper-fraction or decimal form — 7/12 stays 7/12, but 1 1/2 becomes 3/2 or 1.5 on request.

What the calculator does inside
For 2 1/4 − 1 2/3, the tool matches the fraction parts first — quarters and thirds become twelfths — then regroups one whole because 3/12 cannot cover 8/12: 2 3/12 becomes 1 15/12. Subtracting leaves 7/12, already in lowest terms. Every step is the same arithmetic the guides teach, shown so the answer can be checked rather than just copied.
The converters run the companion skills. The improper converter applies multiply-add-keep (2 3/4 → (2 × 4 + 3)/4 = 11/4), and the decimal converter divides the fraction part out (3/4 = 0.75, so 2 3/4 = 2.75). Between the three tools, a mixed number can enter in any form and leave in any form.

Type the first mixed number (2 1/4), the operation (− or +), and the second number, then read the step-by-step result. The tool regroups wholes automatically: 2 1/4 − 1 2/3 shows 2 3/12 − 1 8/12 = 1 15/12 − 1 8/12 = 7/12.
