FRACTIONS

FRACTIONS

by Aarna Gupta

​HELLO EVERYONE! IN TODAYS'S LECTURE WE ARE GOING TO LEARN ALL ABOUT FRACTIONS.

​

​WHAT ARE FRACTIONS?

​Whenever we want to denote our favourable part or the part which has to be highlighted with respect to the total number of parts, we make use of fractions.

​

​For Example: I have a pizza with me and I cut it into 4 pieces and then have 1 of them so I would say that I have eaten one fourth of the pizza.

​And three fourth of pizza is left. This means that I have consumed one part of the pizza out of the four parts which I had and three parts are still left.

​PARTS OF FRACTION

​The part which has to be highlighted is known as the numerator and the total number of parts are taken in the denominator.

​For Example: 4/7

​here 4 is the numerator and 7 is the denominator i.e. I have a total of seven parts and I have consumed/used four of them.

​

​In 1/4 , 1 is the numerator whereas 4 is the denominator.

Multiple Choice

IDENTIFY THE NUMERATOR IN 2/5

• 5

• 2

Multiple Choice

IDENTIFY THE DENOMINATOR IN 5/7

• 7

• 5

Multiple Choice

DENOMINATOR IS:

• THE FAVOYURABLE PARTS

• THE TOTAL NUMBER OF PARTS

Multiple Choice

I HAD 5 PIECES OF CHOCOLAT AND I ATE 3 OF THEM. IF I CONVERT THIS DATA INTO FRACTION GTHE NUMERATOR WILL BE?

• 4

• 3

• 5

• NONE OF THEM

Multiple Choice

I HAD 5 PIECES OF CHOCOLAT AND I ATE 3 OF THEM. IF I CONVERT THIS DATA INTO FRACTION GTHE DENOMINATOR WILL BE?

• 4

• 3

• 5

• NONE OF THEM

​TYPES OF FRACTIONS

​(1.) LIKE FRACTIONS: The fractions with the same denominator are known as like fractions. For example: 2/5, 4/5, 1/5, 3/5 and so on

​

​(2.) UNLIKE FRACTIONS: The fractions with different denominator are known as unlike fractions. For example: 3/7, 5/8, 3/5 and so on

​ADDITION AND SUBTRACTION OF LIKE FRACTIONS

​We know that like fractions are those which have the same denominators.

​To add like fractions we simply add the numerator and the denominator remains the same. The same rule applies for subtraction too.

​Let's have a look at the examples to make this more clear.

​

​1. 1/4 + 2/4 = 3/4 2. 3/8 + 1/8 = 4/8

​3. 6/8 - 4/8 = 2/8 4. 4/5 - 1/5 =3/5

​

​NOW SOLVE THE QUESTIONS GIVEN AHEAD IN THIS LESSON TO GRAB THIS CONCEPT.

Multiple Choice

5/11 + 4/11 = 

• 10/11

• 11/11

• 1/11

• 9/11

Multiple Choice

9/14 - 6/14

• 15/14

• 3/14

• 1/4

• 0

Multiple Choice

3/6 + 2/6 = 

• 5/6

• 4/6

• 5/6

• 1/6

​EXAMPLES OF EQUIVALENT FRACTIONS.

​1/2 = 2/4 = 3/6 = 4/8 = 5/10 AND SO ON.........

​1/3 = 2/6 = 3/9 = 4/12 = 5/15 AND SO ON........

​

​NOW IT'S YOUR TIME TO TELL MORE EXAMPLES.

​MIXED FRACTIONS

​These fractions contain a whole number part and a fractional part.

​Example: 1 1/4 we read them as one; one by four

​By this we mean to say that 1 whole+ one fourth of the total

​

​Suppose Aanya ate 2 pizzas and a half pizza

​We will say it as 2-1/2

​This is an example of MIXED FRACTION.
