Obviously 64 is not 80% of 200.
64/x = 80/100
Cross multiply and solve for x.
To find the number that 64 is 80% of, you can set up a proportion.
Let's call the number you're looking for "x".
The proportion can be set up like this:
64 / x = 80 / 100
To solve for x, you can cross-multiply and then divide:
(64 * 100) / 80 = x
6400 / 80 = x
80 = x
So, 64 is 80% of 80.
