Adding and Subtracting Like Fractions 150 150 SchoolTutoring Academy

Adding and Subtracting Like Fractions

Fractions with same denominators are called like fractions. Like fractions can be added and subtracted very easily. Simply add or subtract the numerators to get the resultant numerator and write the result over the common denominator which would be same as that of the two fractions. If needed the final fraction can be reduced to…

Equivalent Fractions 150 150 SchoolTutoring Academy

Equivalent Fractions

  Equivalent fractions are the fraction that have same value or represent the same part of a whole, even though they look different. If we multiply or divide both numerator and denominator by the same number, the value of fraction remains same.   If we multiply both the numerator and denominator of 1/2 by 2…

Least Common Multiple 150 150 SchoolTutoring Academy

Least Common Multiple

Least common multiple of two (or more) numbers is the smallest number that is a multiple (product of the number with any other number) of both the numbers. For example 6 is the smallest multiple of both 2 and 3. Therefore, LCM of 2 and 3 is 6. Let’s try to find least common multiple…

Comparing Fractions with Like Denominators 150 150 SchoolTutoring Academy

Comparing Fractions with Like Denominators

A fraction is representation of a part of a whole. It is written as where a is numerator which tells the number of equal parts and b is denominator which tell how many parts the whole is divided into. Sometimes we need to compare two fractions. The two fractions may or may not have same…

Compare Unlike Fractions 150 150 SchoolTutoring Academy

Compare Unlike Fractions

A fraction consists of two numbers separated by a line represented as a/b. It represents the parts of a whole. The top number, called numerator, tells how many parts there are and the bottom number, called denominator, tells the total number of parts the object is divided into. Fractions with different (unlike) denominators are also…

Law of Cosines 150 150 SchoolTutoring Academy

Law of Cosines

Law of cosines relates the lengths of sides of an oblique triangle (triangle that is not right-angled) to the cosine of one of its angles. This law is also known as cosine formula or cosine rule. The law of cosines can be used to find the third side of triangle when two sides and the…

Introduction to Fractions: Basics and Types of Fractions

A fraction represents a part of a whole. A fraction is written in the form:     where a is the numerator, and b is the non-zero denominator. The line separating the numerator and denominator is the fraction bar. The numerator represents the number of equal parts and the denominator indicates number of parts make…

Similar Figures 150 150 SchoolTutoring Academy

Similar Figures

The two figures that have same shape but different size are said to be similar. The angles of similar figures measure the same but corresponding sides are in proportion i.e when two figures are similar the ratio of the length of the corresponding sides are equal.  Any two corresponding sides of two similar figures have…
