100% of 45 is 45 itself. So, use the following relationship
If 45 = 100%
Then 69 = x
x = 69 * 100/45 = 153.33%
Then,
% increase = % final - % initial = 153.33% - 100% = 53.33%
That is it.

The equasion I leared was
"Percent / 100 equals "is" / "of" where "is" is the number by the word "is" in a problem and "of" is the number following the word "of". In this case, you don't have the word "of" but you can easily rewrite.
69 is what percentage increase of 45?
Then you have a fractional equasion.
X 69
--- = ---
100 45
So solve this, you "cross multiply" the numerator on the left side with the denominator on the right side and set that equal to the numerator on the right side and the denominator on the left side.
45 * x = 6900
Then, to get "x" by itself you divide both sides by 45:
x = 153 & 1/3.
So 69 is 153.3% of 45.
Since they're asking about an "increase" -- you need to subtract 100% (the base number) first.
Thus it is a 53.3% increase.

To find the percent of increase (or decrease) you do the following:
Find the difference in the two numbers. 69-45 = 24
Now take the difference and divide it by the original value. 24/45 = .53333333333....
To find the percent multiply by 100 to convert the decimal to a percent. .533333333... * 100 = 53.3% or 53 2/3%
Hope this helps and makes sense. Good luck. :)

69/45 = 1.53 then the increase is 53%.
An increase of 100% will bring 45 to 90. 45 + 45*100/100)
an increase of 0 will bring 45 to 45 (45 + 45*0/100)
an increase of 50% will bring 45 to 67.5 (45 + 45*50/100)

If 45 = 100
then 69 = ?
69 x 100 / 45 = 153.33
153.33 - 100 = 53.33 % increase.

Increase = 69 - 45 = 24
Percent increase = (24/45) * 100% = 53.3%

do 69 times 100 then divided by 45 to find out that an answer of 153.33% so since 45 would be 100% just subtract 100 from 153.33 to get an answer of 53.33% as the percent increase

here it is;
(69-45 )/45=.53*100=53%
