Calculator Multiplication of Mixed Numbers



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.

3 3/4 * 2 2/5 = 9/1 = 9

Spelled out: nine.

Calculation steps

  1. Conversion a mixed number 3 3/4 to an improper fraction: 3 3/4 = 3 3/4 = 3 · 4 + 3/4 = 12 + 3/4 = 15/4

    To find a new numerator:
    a) Multiply the whole number 3 by the denominator 4. Whole number 3 equals 3 ·4/4 = 12/4
    b) Add the answer from the previous step 12 to the numerator 3. New numerator is 12 + 3 = 15
    c) Write a previous answer (new numerator 15) over the denominator 4.

    Three and three quarters is fifteen quarters.
  2. Conversion a mixed number 2 2/5 to an improper fraction: 2 2/5 = 2 2/5 = 2 · 5 + 2/5 = 10 + 2/5 = 12/5

    To find a new numerator:
    a) Multiply the whole number 2 by the denominator 5. Whole number 2 equals 2 ·5/5 = 10/5
    b) Add the answer from the previous step 10 to the numerator 2. New numerator is 10 + 2 = 12
    c) Write a previous answer (new numerator 12) over the denominator 5.

    Two and two fifths is twelve fifths.
  3. Multiply: 15/4 · 12/5 = 15 · 12/4 · 5 = 180/20 = 9 · 20/1 · 20 = 9
    Multiply both numerators and both denominators. Then simplify the resulting fraction to its lowest terms GCD(180, 20) = 20. In the following intermediate step, cancel by a common factor of 20 gives 9/1.
    In other words, fifteen quarters multiplied by twelve fifths equals nine.

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.
