Imagining you have one whole cake and you need to share the cake among you and your friends.
Here come the problems, to be fair, we should share the cake equally.
I cut the cake equally to eight pieces and share it with 7 of my friends.
Each of us getting 1/8 of the whole cake.
When one of my friend - Lily is sick and refuse to eat the cake. She cake the cake to me.
Then I get 2 / 8 of the whole cake. By simplification, I get 1 / 4 of the whole cake.
When it comes to include operation in fraction, it follows BODMAS rule as whole number.
What is BODMAS ? BODMAS is the precedence rule when we are solving equation.
B - Bracket
O - Power of / root
D / M - Division / Multiplication (from left to right)
A / S - Addition / Subtraction (from left to right)
So, when there is a equation, we need to solve all those grouped in one bracket, then follow by power of / root of a number , then division / multiplication (left to right because they are in same level of precedence), then addition / subtraction (left to right because they are in same level of precedence as well).
Fraction have numerator / denumenator.
Remember, division bar / can be treated as division as well.
What is complex fraction ?
Complex fraction is a fraction where numerator or denumenator is also a fraction.
No worry, solving a complex fraction is nothing much more difficult than fraction.
First, simplify the complex fraction to simpler form before doing + / -
You have to treat division bar as division.
When you divide a fraction a by another fraction b, you may just change to multiplication by reversing numerator and denumerator of fraction b.
You should need to change the fraction to similar denumerator before doing + / -.
In short, please do refer to the notes below for extra explaination.
