Mixed numbers are combinations of whole numbers and fractions. For example, is a mixed number. It represents 1 whole like a whole pie more.
Converting a Mixed Number to a Fraction. The number 1 can also be expressed as so the number is the same as Let’s try another mixed number: If 1 is the same as then 3 must be Now add: Let’s try one final example. The mixed number is the same as That’s because Now add:
There is an easier way to do this calculation. Let’s work again with Multiply the whole number 3 by the fraction denominator 2, then add the fraction numerator 1. Express the result as a fraction with the same denominator as the fraction in the original mixed number. So for you calculate:
Take as another example:
Converting a Fraction to a Mixed Number. You can work the same calculation backwards. If you are asked to express as a mixed number, simply divide the numerator 8 by the denominator 3 to get Similarly, can be expressed as or (Don’t forget to convert your answers to their lowest terms.)
Converting a Mixed Number to a Decimal. You can also convert mixed numbers to decimals. Take the mixed number, make it into a fraction, then divide the numerator by the denominator to get the decimal. Here are two examples:
