Understanding fractions: Part 1

I know lots of children find fractions and decimals quite daunting. Trust me, if you understand the meaning of it an understand how to look at the topic in a certain way you will be able to any kind of problem immaterial of how twisted it is. So, let's start!

What is a fraction:
A fraction is a part of something. For example


Say I get a pizza, So the first picture represent 1 full/whole pizza.
Pic 2: I cut the pizza into 2 parts, now what is the total number of parts of the pizza ?
two (one in white, one in yellow)
say, the yellow part I am going to eat and white is for you.
So, what fraction (part) of the pizza are you eating?

= part you eat
    ___________              
      total parts

=   white part
_____________
  yellow+white

=       1
      _____
         2
Now assume that yellow is the part you eat and white is the remaining, apply the same logic as above, where the numerator is the number of pizza parts eaten and denominator is the total parts cut.

Now try to solve these problems.
1.

2. How will you write in fraction the shaded portion of the hexagon?

Types of Fractions: Proper fraction & Improper fraction

Proper and Improper fractions: As discussed in previous topic  www.blogger.com/blogger.g  a fraction is a part of something.  Hence fractions are always less than 1. Let me explain this, As in the pizza figure  www.blogger.com/blogger.g  a pizza is cut in 4 parts. Say we are calculating the number of parts Anne ate. Fraction of pizza ate = (Number of parts Anne ate)/ (Total parts) If Anne eats 4 parts then the fraction is, Fraction of pizza ate= 4/4= 1, that is one full pizza so any part eaten less than all 4 pizza parts will give us an answer less than 1. Try your answers assuming she ate, 2 parts and 3 parts. Whats your answer? Is it less than 1? So when in the fraction the numerator is less than the denominator or the fraction is less than 1 its a proper fraction. eg; 3/4 (3<4, hence proper fraction because 3/4=0.75 which is less than 1) when in the fraction the numerator is more than the denominator or the fraction is more than 1 its an improp...

What is a number line, how does it look, why we need them?

Image
Number line A number line is an imaginary line which represents 0 in the middle of the line, positive numbers on the right side of 0 and negative numbers on the left side of the line. It's a never ending line and thats why it is represented by arrows on both sides. This is how a number line is represented, Why do we need them? It's easy to visualise numbers in terms of distance. Many times it helps in doing addition, subtraction in better way. Please note: For both positive and negative numbers, the more the number is towards right side of the number line the bigger it is , for example 6 is on right of 5 in number line so it's bigger similarly for negative numbers, the more the number is towards right the bigger it is, for example -1 is on right of -3 in number line so it's bigger. Understanding number line with real life example If you get confused about it in exam or anytime think of it with this example; Say you have 100$ with you. Say ne...
