Percentage is parts of 100.
An example: 2% is 2100
So we need to convert your 1623% into parts of 100
Write 1623 as 16+23
Change into fractions of 100 parts
16100+23100
But 23100=23×1100
Now we have 16100+2×13×100
16100+2300
Before we can add these directly we need to make the bottom numbers the same (denominators)
Need to change the 100 in 16100 into 300.
Multiply by 1 but in the form of 33
16×3100×3+2300
=48300+2300=50300
Simplifying gives:
=50÷10300÷10=5/30 =
5÷530÷5=(1/6)
