The Basic Concepts of Ratios 

Once the basic arithmetic operations are learnt there are other concepts that have to be learnt. It is better to learn the ratio of similar objects. This concept can be very helpful in solving the mathematical problems. One needs ratio help to understand the term better. The math ratio problems are fun to work with. Once many problems are solved the concept will become clearer. It is better to get help with ratios as this concept has to be learnt clearly so that other concepts like proportion have to be learnt. Both are related to each other. So, one has to understand the previous concept well. Only then proportion can be understood well.

The ratios in math define relationship between objects which are of similar kind. If there are 5 yellow balls in a basket and 4 white balls in a basket then the ratio is nothing but 5:4. So, the notation is obtained by using colon between the numbers. So, the relationship between the yellow balls in the basket and the white balls in the basket is defined and helps us to understand better. The standard size of the television can also be expressed using this term.  The term has a history as well. But it is very difficult to tell exactly when the term became common. But it is a very important in the mathematical world. Proportion can also be learnt using this term. So, it is better to learn the term very well. It is basically written in the form of a fraction. Fraction can also be written as a decimal. The vice-versa can also be done. So, to understand the basic understanding of fractions can also be very helpful. This term is also used with percentages. If both the numerator and the denominator are multiplied by the same number the value of the fraction does not change. It means the value of the fraction remains the same even after the multiplication. This concept can be very helpful. Having problem with real numbers keep reading my upcoming posts, i will try to help you.

The fractions can also be reduced to smaller ones. This can be done by dividing both the numerator and denominator with common factors. This will help in reducing the fraction to a smaller fraction. This can be done only if there are common factors for both the numerator and the denominator. Both the numerator and denominator must be divided by the same number. They should be divided till the fraction becomes smallest.
