Explanation:

To solve this problem, turn it into an equation. Here are some tips:

  1. "Is" means "equals", so wherever you see "is", use a = sign.
  2. "Of" means "multiplication", so use a xx sign when you see that word.
  3. 25% is the same as 25/100 as a fraction, or 0.25 as a decimal. I'm going to use the fraction form in the equation.
  4. Use variables for the things you do not know. I will use the variable x for "what number".

stackrel(x)overbrace"What number"stackrel(=)overbrace"is"stackrel(25/100)overbrace"25%"stackrel(xx)overbrace"of"stackrel(64)overbrace"64"

x = 25/100 xx 64

x = 25/100 xx 64/1

uarr Anything divided by 1 is itself, so this does not change the value of the expression

x = (25 xx 64)/(100 xx 1)

x = 1600/100

x = 16

16 is 25% of 64.
