fractional notation calculator

Previously we have discussed about area of equilateral triangle calculator and In today's session we are going to discuss about Fractional Notation Calculator, It will help the students for the study of 8th grade math, which will enhance the skills of the child to learn about the fractional notation.  We can find online information about cbse class 12 home science question bank which will guide the students to learn about the pattern of the paper in the fore coming examination. Now if we talk about the fractional notation, then we say that all the decimal numbers can be expressed in the form of the fraction numbers. So we simply have to remove the decimal and the number of digits after the decimal will be replaced by the power of 10 at the denominator.  Let’s look  at the following example :
1.23 can be written as 123 / 100. But here it is in the lowest form as it cannot be further divided into the lower form. (Know more about fraction in broad manner, here,)
 Similarly, we can take other numbers and see that the number can be converted into simpler form of the fraction number. So if we have the number 0.25, it can be written as: 0.25 = 25 / 100
On dividing the numerator and the denominator by 25 we get the fraction as ¼.
 Similarly we look at the percentage of any number and see how to convert it into the fractions. Suppose we need to convert 15 % in form of the fraction, then we say that 15% can be written as 15 / 100. Now we observe that   the HCF of the numerator and the denominator is 5, so we say that we divide the numerator and the denominator by 5 and we get 3 / 20.  So the percentage 15 % can be expressed as the fraction 3/20.
So the fraction notation convert will convert the various values which are either in the form of percent or decimal in the form of fraction numbers.
In the next session we will discuss about Simplifying Rational Expressions

and Read more maths topics of different grades such as how to solve inequalities with fractions in the upcoming sessions here.
