Fractions in MV Workstation
Exact arithmetic that never rounds: add, subtract, multiply and divide fractions and mixed numbers, simplify, compare, and change between fractions, decimals and percentages. Type 1/2 + 1/3 and see 5/6.
Type the maths the way you write it and MV Workstation shows the exact answer, the working and, where it helps, a picture you can drag.
Things to try
| What it is | Type this |
|---|---|
| Add fractions | 1/2 + 1/3 |
| Divide fractions | 3/4 ÷ 3/8 |
| Mixed numbers | mix(2, 1, 3) + mix(1, 3, 4) |
| A recurring decimal | rec(0.1, 6) |
| Fraction of an amount | 2/3 * 90 |
Tools
- Calculate: Exact step-by-step arithmetic with fractions: 1/2 + 1/3 becomes 5/6, with every step shown.
- Simplify a fraction: Cancel down to lowest terms, with the common factor found by prime factors.
- Fraction · decimal · percentage: See one number as a fraction, a mixed number, a decimal (recurring ones too) and a percentage.
- Compare: Which is bigger? Put fractions over a common denominator and compare, step by step.
Pictures you can drag
- Fractions you can see: Bars, pies or a number line show what a fraction is; multiply top and bottom to see equivalent fractions.
- Adding and subtracting fractions: Cut both fractions into equal pieces (a common denominator), then add or subtract the pieces.
- Multiplying and dividing fractions: Multiply or divide fractions by shading parts of parts, with the answer worked out underneath.
Functions
| Function | What it does | Example |
|---|---|---|
mix(w, n, d) | A mixed number: mix(2, 1, 3) is 2 and 1/3, typeset the way it is written on paper. | mix(2, 1, 3) + mix(1, 3, 4) |
rec(decimal, digits) | A recurring decimal: rec(0, 3) is 0.333…, and rec(0.1, 6) is 0.1666…. The second number holds the digits that repeat; they are typeset with a bar. | rec(0.1, 6) |
