MIXED NUMBERS DIVISION

Mixed Numbers are a type of the number system. There are different types of numbers.
  • Whole Numbers
  • Natural numbers
  • Mixed Numbers
  • Integers
  • Fractions
  • Decimals
  • Prime Numbers
  • Composite Numbers
Mixed numbers are basically Mixed fractions. There are certain steps followed while dividing Fractions with Mixed numbers. Students can follow the following steps to how to divide mixed numbers.

Step 1. Convert the mixed number into an improper fraction.

Step 2.
Invert the second fraction upside down (this is a reciprocal) on dividing fractions.

Step 3. Then the reciprocal of second fraction is multiplied with first fraction.

Step 4. Shorten the dividing fractions.

The steps to be followed to covert a mixed number into an improper fraction are as follows:

1. Denominator of the fractional part is multiplied by whole number.

2. The number obtained above is inserted as the numerator of the fractional part to that result.

3.The denominator remains the same as of the fractional part of the original mixed number.

INEQUALITIES

The study of inequalities is an important topic under Math. It deals with comparison of 2 values how the relative size or order of two objects, or about whether they are the same or not.
It includes various symbols like:
  • < - lesser than
  • > - greater than
  • = -equal to
  • greater than or equal to
  • lesser than or equal to etc.
Students should under the comparisons and learn to draw conclusions out of them. It is therefore important for students to understand the concepts clearly.
Inequalities have the following properties:
  • Transitivity
  • Reversal
  • Addition
  • Subtraction
  • Multiplication
  • Division properties
Students can learn how to solve problems on Inequalities step by step by observing the solved examples or take the help of the online Inequalities calculator to solve the problems.
