Hi there!
We are told to write a proportion to find what 85% of 120 is. Here is what our model should look like:
[tex] \frac{x}{120} = \frac{85}{100} [/tex]
Now, we use cross multiplication to simplify the equation down.
[tex]100x = 10200[/tex]
Finally, just solve for x to get a value of 102. Therefore, 102 is 85% of 120. Hope this helps and have a fantastic day!
