Fractions

Numerator tells you how many slices you have taken,
Denominator tells you,how many pieces have pizza (example) was cut into.

Picture showing numerator and denominator

Also we can simplify fractions.

As you see

Think of a number that would be divisible by numerator an denominator.

Fraction looks like this

It will always be different than this

You call that number
three quarters

Area

Everybody sometimes finds area and perimeter is same. There is difference between them.
To find area of shape you have to multiply length and breadth together to find out.
Formula is

L

B

L=length

B=breadth

Example of how to find it out

A=7

14

=

98

Area is to find space inside of the shape

There might be hard shapes to find the area of it.

You might divide the shape with a line, to make it easier

First try to find out the area of the A shape and then B shape, after add them up

Different Methods to
Multiply

There are three different ways to multiply numbers.
1.New Method
2.Short Method
3.Grid Method

-------------------

1

For eg. Let's take

398
85

1.First multiply 398

to 5

2.Than you multiply 398 by 8 than the answer to 10. Because it's hard to multiply 80 by big number so it's easier to split them up

3.Next add them up to get your answer
