16 is 25% of what number

25% of 16 can be written as:

25% * n = 16 (Where n represents the number which 16 will be 25% of)

25% * n is the same thing as saying:

1/4 * X = 16

X/4 = 16

X/4 * 4 = 16 * 4

X = 64

This may be a bit confusing, if you require clarification, let me know!

So the question is 16 is 25% of what number (x)

In math

"is" means equals

"of" means times

The question translates to

16 = 25% * x

16 =.25x

16/.25 = x

64 = x

x = 64

16 is 25% of 64
