The elements could be anything like picture, numbers, alphabets. The repetition of elements and the order of […]
Read More →Irrational Numbers – Definition, Examples, Properties Definition and Properties of Irrational Numbers Irrational Numbers An irrational number is a real number that cannot be expressed as a simple fraction, i.e., it cannot be written in the form a/b, where a and b are integers and b≠0. This means irrational numbers have non terminating, non-repeating decimal […]
Read More →Equivalent Fraction Definition: Equivalent fractions are the fractions that have different numerator and denominators but represent the same or equal value. Example: 1/2, 2/4, 3/6 and 4/8 all are equivalent fractions, because they all are equal to 1/2. Similarly 10/20, 20/40, 30/60 and 40/80 all are equivalent fractions, because they all are equal to 1/2. […]
Read More →Like and Unlike Fractions Like Fractions We see a group of fractions. 1/3, 2/3, 4/3, 7/3, 8/3, 10/3 We observe that in the group, denominator of each fraction is 3, i.e., the denominators of all the fractions are equal. Definition: Fractions with same denominators (bottom […]
Read More →Fraction – Introduction Definition: In mathematics, A fraction is a numerical value, that represents a part of a whole. When an object or group of objects is divided into equal parts, then each individual part is a fraction. A fraction can be a portion of any quantity out of the whole and whole can be […]
