Percentage is parts of 100.
Note that the % sign is like units of measurement. Its value to be considered as:
1
100
An example: 2% is the same as
2
×
1
100
=
2
100
So the
16
2
3
%
is the same as
16
2
3
×
1
100
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Write
16
2
3
as
16
+
2
3
Change into fractions of 100 parts
16
100
+
2
3
100
But
2
3
100
=
2
3
×
1
100
Now we have
16
100
+
2
×
1
3
×
100
16
100
+
2
300
Before we can add these directly we need to make the bottom numbers the same (denominators)
Need to change the 100 in
16
100
into 300.
Multiply by 1 but in the form of
3
3
16
×
3
100
×
3
+
2
300
=
48
300
+
2
300
=
50
300
Simplifying gives:
=
50
÷
10
300
÷
10
=
5
30
=
5
÷
5
30
÷
5
=
