Recall that fractions are numbers that represent parts of a whole number, and are written as a number over another. The number above is the numerator, while that below is the denominator; (that is numerator/denominator).
If the numerator is lesser than than the denominator, then the fraction is less than '1'. If the numerator is greater than the denominator, that implies that the fraction is greater than '1'. However, if the numerator and denominator are equal (or same), then the fraction is equal to '1'.
The numerator of a fraction simply tells us how many parts we've got out of the total equal parts it had been divided into (that is; denominator). For instance, in 2/4, the numerator, that is "2" tells us we have two parts of something (e.g pizza) while the denominator '4' tells us that the two pizzas had been divided into 4 equal parts.
Please read on the conversion of decimal to fraction here.
If the denominator of a fraction is a tenth, hundredth, thousandths, tenth of thousandths and so on; we can easily count the number of zero(s) of the denominator, write it down, after which we'll write the value of the numerator on the rightmost side. Always add a dot after the first zero. This is shown below:
Convert the following fractions to decimal:
1/10 = 0.1
1/100 = 0.01
1/1,000 = 0.001
1/10,000 = 0.0001
Note: Knowledge on place value of numbers will be required when using this method.
Please read more on the place value of numbers here.
If the denominator isn't a tenth, hundredth, thousandths and so on, we may still multiply the numerator and denominator by a value that makes (the denominator) a tenth, hundredth or thousandths. This is shown below:
Convert the following fractions to decimal:
Example 1:
Multiply the numerator and denominator by 2 (to make the denominator a tenth)
Example 2
Multiply the numerator and denominator by 4 (to make a the denominator a hundredth)
Example 3
Multiply the numerator and denominator by 5 (to make a the denominator a thousandth)
Please read on the multiplication and division of fractions here.
Note: This method is not always applicable, thus making method 2 more accurate when dealing with all fractions.
This is the division method. We can convert decimal to fraction by using the decisive (or division) method.
To convert a fraction to a decimal using the division method, simply divide the numerator (top number) by the denominator (bottom number). You will need to add zero(s) or an appropriate positive number and a decimal point as needed to continue the division until you get a remainder of zero.
Please read on the addition and subtraction of fractions here.
These are explained through the steps below:
Step 1: Identify the top number (numerator) and bottom number (denominator) of the fraction.
Step 2: Divide the numerator by the denominator. If the denominator is larger than the numerator, you'll write down a zero and dot (decimal point), Next, you will minus this value of zero from the numerator, which still gives you the same numerator. For example, in dividing 1/2, since the denominator '2' is larger than the numerator '1', we will simply write down a zero and a point (that is 0 point). Next, minus zero from 1 (1 - 0 = 1).
Step 3: Next, we'll add a zero to the numerator (if there's isn't a number after it). In our example above, this makes the numerator 10. However, if there's a number after the numerator, we'll bring down the number. See the images below:
Step 4: We'll divide the 10 (derived in step 3) by the denominator and this gives us 5 remainder 0. That is (10/2 = 5) The value of 5 is added after the point, eventually giving us the answer 0.5 . This will be our final answer in this instance.
Step 5: If we are yet to reach a remainder of zero, we'll keep bringing down numbers until we get a remainder of zero. See the images below:
Step 6: If a repeating pattern keeps appearing, this means that the decimal won't terminate. Therefore, round up to the desired decimal place (e.g., tenths, hundredths, thousandth, etc).
Step 7: When working with mixed fractions, for instance '2 1/2', either convert it to improper fraction and then divide, or simply convert the fraction part and add it to the whole number (2 + 0.5 = 2.5).

The division of fractions are further shown through the images below:
Note: In the division method, the numerator is called the dividend with the denominator is called the decision.

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

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
