We want to find the unknown number, which represents the portion, so we need to use the equation:

rate * base = portion

In this case, we know the rate is 64% and the portion is 57, so we can plug those values in:

64% * base = 57

To solve for base, we can divide both sides by 64% (or 0.64):

base = 57 ÷ 0.64

base ≈ 89.1

Therefore, 64% of approximately 89.1 is 57.
