Answer: x = 52
Step-by-step explanation: Well <em>percent</em> means <em>over 100</em> so we know that 25% means 25/100. <em>Of</em> means <em>times</em>, <em>what number</em> means <em>x</em>, <em>is</em> means<em> equals</em>, and <em>12</em> means <em>12</em>. So we can translate this problem into an equation.
So we have the equation 25/100 · X = 13
Notice that 25/100 can be reduced to 1/4.
So rewriting our problem we have X/4 = 13.
To get rid of the fraction, we multiply both sides of the equation by 4 and we have <em>x = 52</em>.
This means that 25% of <em>52</em><em> </em>is 13.
