Answer: 126.76056338%
Step-by-step explanation: To answer the question what percent of 71 is 90, we translate the question into an equation.
We have <em>"what percent" </em>which we can represent by the variable X. Next we have <em>"of 71"</em> which means "times 71" and <em>"is 90" </em>means "equals 90."
Now to solve for <em>x</em>, since <em>x</em> is being multiplied by 71, we need to divide by 71 on both sides of the equation.
<em />
On the left side of the equation the 71's cancel and we have <em>x</em>.<em> </em>On the right side of the equation we have 90 divided by 71 which is 1.2676056338.
Now, remember that we want to write our answer as a percent. To write 1.2676056338 as a percent, we move the decimal point two places to the right and we get 126.76056338%.
