Converting a fractional notation is where a whole of a fraction is converted so that it is seen in the form of a fraction. An example of this is 1 ½ as a fractional notation is 3/2.

  • Methods
The method that you use to do this is simple. You need to take the whole number and multiply it by the denominator. In this case the denominator is 2. You then add this number to the number at the top of the fraction, in this case it is 2 + 1 and then use that as the top number in the fraction. The denominator should not change.

This is used frequently in school based math and is taught to children as a part of their math education.

  • Using fractional notations
It is used in the wider world to find out how many equal parts or numbers there are when there is a whole number and a fraction together. This is a simple way to work this out although with large numbers it may be best to use a calculator so that you do not get stuck on the multiplication.

  • Fractional notations in industry
Fractional notations are used in many different industries. These can range from science based industries to multiplying how much cake you would need for an event and the ingredients this would take. There are many industries where people will work out simple fractional notations out in their heads and not even know what a fractional notation is.

  • Advanced math
You can start to add together fractional notations but you have to create a denominator that is the same value in both fractional notations that you are adding together and may have to change the ½ to 2/4 or another equivalent fraction to get this right.

1 1/10=(1×10+1)/10=11/10,so the answer is 11/10.

Multiply the integer of the mixed number by 1 in an appropriate form and add the fraction. In your example, the appropriate form is 1 = 10/10. This multiplier is formed by dividing the denominator by itself.
  5 1/10
  = 5*(10/10) + 1/10
  = 50/10 + 1/10
  = (50 + 1)/10
  = 51/10
_____
In the general case, you have
  a + b/c
  = a*(c/c) + b/c
  = ac/c + b/c
  = (ac + b)/c

Once you recognize the pattern, you can skip the intermediate steps and write down the answer directly.
  5 1/10 = (5*10 + 1)/10 = 51/10

Multiply and divide by the denominator of the fraction.  Example  4 2/3 = (4 2/3)*3/3 = (4*3 + (2/3)*3)/3 = (12 + 2)/3 = 14/3  In general  a + b/c = (ac + b)/c  4 + 2/3 = (4*3 + 2)/3 = 14/3

When you write any fraction in terms of the numerator and denominator then it is known as fractional notations. For example, in the fraction 11/2, 11 is the numerator and 2 is the denominator therefore, mentioning the denominator and numerator is known as fraction notations.

In 6/7, 6 is numerator and 7 is denominator.

Multiply 5 X 9 to get the rest of the numerator = 45
add to existing numerator = 45+7 = 52

= 52/9
