convert percentage to the decimals and fraction

Percentage is a rate, number, or amount in each hundred and it is write like this: 90%if you have got 95/100 and you want to convert it to the decimals you have to divide top number by the denominator to get the decimal number in this case going to be 0.95 but we can have other example like:  9/10= 0.9 or 5/25= 0.2 If you want to write 90% or 0.9 as a fraction you have to write it in the same way as 90/100 and than you need to simplify it like this 90/100= 9/10 we can have other examples like: 33/99= 11/33 and this is = 1/3

AREA OF CIRCLE

 if you want to find the area you have to times (r*r)* 3.14

area & Perimeter of Square & Rectangular

Square:

area: A=S*S

PERIMETER:  P=S+S+S+S   OR       P=S*4

Rectangle:

area:   A=L*W

perimeter: p=2{L+W}  OR  P= 2L+2W

S=SIDE
A=AREA
P=PERIMETER
L= LENGTH
W= WIDTH

Slice a pizza, and you will have fractions

1/2	1/4	3/8
(One-Half)	(One-Quarter)	(Three-Eighths)
The top number tells how many slices you have  The bottom number tells how many slices the pizza wascut into. Some fractions may look different, but are really the same, for example: 4/8 = 2/4 = 1/2 (Four-Eighths) Two-Quarters) (One-Half)

It is usually best to show an answer using the simplest fraction ( 1/2 in this case ). That is calledSimplifying, or Reducing the Fraction

Q1}

3/8	+	1/4	=	?
	+		=

Fraction is very easy.

I give you an example:

this is a half:

this is a full:

this is a Quarter:
