Calculator subtracting mixed number and fraction



The 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.

1 3/5 - 5/6 = 23/30 ≅ 0.7666667

Spelled result in words is twenty-three thirtieths.

Calculation steps

  1. Conversion a mixed number 1 3/5 to a improper fraction: 1 3/5 = 1 3/5 = 1 · 5 + 3/5 = 5 + 3/5 = 8/5

    To find new numerator:
    a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 5/5 = 5/5
    b) Add the answer from previous step 5 to the numerator 3. New numerator is 5 + 3 = 8
    c) Write a previous answer (new numerator 8) over the denominator 5.

    One and three fifths is eight fifths
  2. Subtract: 8/5 - 5/6 = 8 · 6/5 · 6 - 5 · 5/6 · 5 = 48/30 - 25/30 = 48 - 25/30 = 23/30
    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(5, 6) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 6 = 30. In the next intermediate step, the fraction result cannot be further simplified by canceling.
    In words - eight fifths minus five sixths = twenty-three thirtieths.
