36.25= 45.5% of ____
aev [14]

Answer:

36.25 is equal to the 45.5% of 79.67

Step-by-step explanation:

To solve this you just have to find the value that represents the 100%.

To do this, you can use the Rule of Three that allows you to solve problems of proportions.

In this case, you know that the 45.5% of the magnitude <em>X </em>is 36.25, now you have to find the value which corresponds to the 100%.  

Mathematically it will be:

\frac{X}{36.25} =\frac{100}{45.5}

Then you have to solve the equation to find <em>X</em>:

X=\frac{100}{45.5}*36.25

And finally, the answer is:

X=79.67
