Welcome to aptitude tricks

Main Concepts and Results

• A fraction is a number representing a part of a whole. This whole

may be a single object or a group of objects.

• A fraction whose numerator is less than the denominator is called a

proper fraction, otherwise it is called an improper fraction.

• Numbers of the type

5 4 1 3 ,8 ,2

7 9 5 etc. are called mixed fractions

(numbers).

• An improper fraction can be converted into a mixed fraction and

vice versa.

• Fractions equivalent to a given fraction can be obtained by

multiplying or dividing its numerator and denominator by a non-

zero number.

• A fraction in which there is no common factor, except 1, in its

numerator and denominator is called a fraction in the simplest or

lowest form.

• Fractions with same denominators are called like fractions and if

the denominators are different, then they are called unlike fractions.

• Fractions can be compared by converting them into like fractions

and then arranging them in ascending or descending order.

• Addition (or subtraction) of like fractions can be done by adding

(or subtracting) their numerators.
