Subtracting Fractions from Whole Numbers Subtracting Fractions from Whole Numbers Subtracting Fractions with Whole Numbers and Different Denominators is used very much in day today life and it is very easy to understand the subtraction of fractions with whole numbers and different denominators. When we talk about the subtraction of fractions and whole numbers then in this type of problem solving we have to follow some steps that are as defined: Rule (I): when there is an expression in which whole number is subtracted from the fraction then first of all write the whole expression in the fraction format means change the whole number into the fraction it will describe by an example: Example: if an expression is 5 / 2 – 2 then it will written as 5 / 2 – 2 / 1 (since, 2 = 2 / 1) or 5/2–2/1=? Rule (II): After it calculate the LCM of the denominators of the fractions in the given expression means for making the denominators equal of each fraction if take the above example then LCM of 2 and 1 is 2. Rule (III) : After calculating the LCM divide it by each denominator and then multiply the answer with numerator of each fraction respectively as understand by the example LCM is 2 then divide 2 by 2 that is the denominator of fraction 5 / 2 and give the answer 1 that is multiplied with 5 and give the answer 5 and 2 also divide by the 1 that gives the 2 and this answer is multiplied with the 2 and gives 4 so it will be written as 5 / 2 – 4 / 2 that shows the fractions have same denominator and it will also be written as (5 – 4) / 2.

Rule (IV): Solve the expression as define by the operators as in above example it solved as subtract the 4 form 5 and denominator will remain same as (5 – 4) / 2 = 1 / 2 (answer). When we talk about subtraction of the fractions with different denominator then it will also be solved as using the above rules we can understand it by taking an example of fractions with different denominators as an expression 1 / 2 – 1 / 4 in this given expression two fractions 1 / 2 and 1 / 4 have different denominator 2 and 4 respectively then it is solved as: Rule (I): First write them in form of fractions that is already in that format and calculate the LCM of denominators of fraction that means LCM of 2 and 4 is 4. Rule (II): after calculate the LCM divide it by each denominator and multiplied the answer with numerator of each fraction as 4 is divided by 2 that gives 2 and then 2 is multiplied with 1 that gives 2 and same with other fraction means LCM 4 is divided by the denominator 4 that gives the answer 1 and then it is multiplied with 1 that gives 1. Improper fractions and the whole numbers are the sub-types of number system. Both number systems can perform the various types of activity to solve the problem that are related to mathematics. So, before performing any operation we need to understand the concept of improper fractions and whole numbers. Improper fractions numbers are the type of fractional numbers in number system. In the specific definition improper number can be define as a fraction that has a numerator value larger than or equal to the denominator value. As we know that fractional numbers are those numbers that can represent the two integer’s values in the form of numerator and denominator numbers. As a name specify that improper fractions means a fraction that is not in proper format. Example: 5 / 4, 10 / 9, 17 / 17 or etc... In the above example we can see that the value of numerator is greater then the value of denominator. This makes it improper fractions. In the fraction there are types of fractions are define: a) Proper fractions: 5 / 6 in this example we can see that the 5 is a numerator value which is lesser then the denominator value 6. So this is proper fraction. b) Improper fractions: 4 / 3 in this example we can see that the value of 4 is a numerator value which is greater then the value of denominator that is 3. So this can be known as Improper fractions. c) Mixed fractions: in this type of fractions the whole values are added with the fraction numbers like 2 ½. Read More About :- Degree of Polynomials
