Mixed number calculator



This calculator performs basic and advanced operations with mixed numbers, fractions, integers, decimals. Mixed fractions are also called mixed numbers. A mixed fraction is a whole number and a proper fraction combined, i.e. one and three-quarters. The calculator evaluates the expression or solves the equation with step-by-step calculation progress information. Solve problems with two or more mixed numbers fractions in one expression.

Result:

4 - 2/5 = 18/5 = 3 3/5 = 3.6

Spelled result in words is three and three fifths (or eighteen fifths).

Calculation steps

  1. Subtract: 4 - 2/5 = 4/1 - 2/5 = 4 · 5/1 · 5 - 2/5 = 20/5 - 2/5 = 20 - 2/5 = 18/5
    For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 5) = 5. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 5 = 5. In the following intermediate step, it cannot further simplify the fraction result by canceling.
    In other words - four minus two fifths = eighteen fifths.
