= (33.5 / 65) x 100 %
= (67 / 130) x 100 %
= 6700 / 130 %
= 670 / 13 %
= 51 7/13 %
= 51.5 % (to 1 dec. place)

A percentage is a proportion between two quantities expressed in hundredths. It is often used to define a portion as a fraction of a whole.

How to find a percentage of a number
Multiply the number by the percentage fraction. For example to calculate 9% of 25000, multiply 25000 by 9/100, that is, multiply 25000 by 0.09.

If your calculator does not have a percent key and you want to add a percentage to a number multiply that number by 1 plus the percentage fraction. For example 25000+9% = 25000 x 1.09 = 27250. To subtract 9 percent multiply the number by 1 minus the percentage fraction. Example: 25000 - 9% = 25000 x 0.91 = 22750.

to find percentage in this case

use the formula (a/b) X 100
here,
a = 33.5
b = 65

(33.5 /65 ) x 100

= 51.53 %

The answer is (33.5/65)*100 per cent = 52.53846%

If you need an algebraic formula for a question like "x is what percentage of y" the answer will be (x/y)*100 per cent

Solve by rationing;

If 33,5 for 65
then ? for 100
------------------------
100*33,5 / 65 = 51,5385 %

33.5 = 65x

x=0.514 or 51.4%.

No problem, it happens to the best of us.
