Calculator Subtracting Mixed Number and Fraction



This calculator performs basic and advanced operations with mixed numbers, fractions, integers, and decimals. Mixed numbers are also called mixed fractions. A mixed number 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 out: twenty-three thirtieths.

Calculation steps

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

    To find a new numerator:
    a) Multiply the whole number 1 by the denominator 5. Whole number 1 equals 1 ·5/5 = 5/5
    b) Add the answer from the 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
    It is suitable to adjust both fractions to a common (equal) denominator for subtracting fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 6) = 30. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 6 = 30. In the following intermediate step, the fraction cannot be simplified further by cancelling.
    In other words, eight fifths minus five sixths equals twenty-three thirtieths.

What is a mixed number?

A mixed number is an integer and fraction acb​ whose value equals the sum of that integer and fraction. For example, we write two and four-fifths as 254​. Its value is 254​=2+54​=510​+54​=514​. The mixed number is the exception - the missing operand between a whole number and a fraction is not multiplication but an addition: 254​​=2⋅ 54​. A negative mixed number - the minus sign also applies to the fractional −254​=−(254​)=−(2+54​)=−514​. A mixed number is sometimes called a mixed fraction. Usually, a mixed number contains a natural number and a proper fraction, and its value is an improper fraction, that is, one where the numerator is greater than the denominator.

How do I imagine a mixed number?

We can imagine mixed numbers in the example of cakes. We have three cakes, and we have divided each into five parts. We thus obtained 3 * 5 = 15 pieces of cake. One piece when we ate, there were 14 pieces left, which is 254​ of cake. When we eat two pieces, 253​ of the cake remains.
