Decimals are numbers that uses a dot (decimal point) to separate a whole number from the fractional part. Recall that the consecutive numbers after the dot are the fractional part, and they show tenths, hundredths, thousandths, tenth of thousandths, hundredth of thousandths and so on.
Please read on prime numbers here.
Fractions are numbers that represent parts of a whole number, and are written as a number over another. The number above is termed the numerator, while that below is the called the denominator. Therefore, fractions are always expressed as 'numerator/denominator'.
A fractions simply tells us how many parts we have (as represented by the numerator) out of the total equal parts it had been divided into (as represented by the denominator). For instance, in the fraction '1/3', the numerator, (that is "1") tells us we have only one entity or thing (e.g meat pie) while the denominator '3' tells us that this means '1' meat pie had been divided into '3' equal parts.

In a fraction, if the numerator is lesser than than the denominator, then the fraction is less than '1'. If the numerator is greater than the denominator, it implies that the fraction is greater than '1'. However, if the numerator and denominator are equals (or same), then the fraction is equal to '1'.
In order to convert a decimal to a fraction, we will have to place the number or digit after the dot (decimal number) as numerator over its place value (e.g tenths, hundredths, thousandths and so on) as the denominator; after which we'll simplify the resulting fraction by dividing the numerator and denominator by their greatest common factor. For example, the decimal 0.5 becomes 5/10; which simplifies into 1/2

Note: A good knowledge on the place value of decimals is very important when converting decimals to fractions.

Amazing facts in Mathematics
The opposite sides of a dice will always give a sum of seven
31,556,926 seconds makes one year
From 0 through 1000, the only number that has the letter 'a' in it is 'one thousand'
÷
The division symbol '÷' is actually called an obelus
Four is the only number in the English language that is spelt with the same number of letters as the number (4) itself
40 is spelt as forty and not 'fourty'. It is the only number that is spelt with letters arranged in alphabetical order
An odd number is a number that cannot be divisible by 2.
Every odd number has an 'e' in its spelling. They include:
555 in Thailand sounds like 'hahaha'. This is because the number '5' means 'ha' in Thailand
In mathematics, 10! means 10 factorial. Below is its calculation:
10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 3628800
Interestingly, 3628800 seconds is the same as 42 days
42 days is the same as 6 weeks
We can therefore say that 10! equals 6 weeks or 3628800 seconds in mathematics
When you multiply 111,111,111 by 111,111,111; the result equals 12,345,678,987,654,321
Notable points in Mathematics
Let's use algebra to explain the simple statement below:
I am a number. When you subtract 3 from me, the result is 9. what number am I ?
Of course we know the answer is 12. You probably guessed it from your mind because it was that simple. The truth is, We could have a much more complicated statement of such; and that is where algebra comes into play.
Now, to apply algebra in the above statement, we use letters or alphabets to represent the unknown number(s). So using algebra, we can write:
Let the number be y
y - 3 = 9
y = 9 + 3
y = 12
The image above shows a right angled triangle. The angle of the above right triangle is denoted as θ. Below are some points to note:
Hypotenuse is always the longest side of the triangle.
Opposite is the side opposite the angle (θ)
Adjacent is the shorter side next to the angle (θ)
Each of Sin θ, cos θ and tan θ are the ratio of sides of the right triangle. They are calculated by using the formula (margic word) sohcahtoa:
soh
Sin θ = Opposite/Hypotenuse
cah
Cos θ = Adjacent/Hypotenuse
toa
Tan θ = Opposite/Adjacent

Circumference is to circle or any other curved surface
Perimeter means the distance around a square or rectangle or polygon.
Perimeter is to square or rectangle or polygon
