The statement "84 is 140% of what" can be directly converted to the equation:

84=1.4x

Now solve for x...

Note: The first reply to your post gives you the general formula for all exercises of this type! The "percent of" equation is "(this) is (some percent) of (that)", where "is" means "equals", "of" means "times", and "(some percent)" is written in decimal form (so "0.50" rather than "50%").

Memorize this, and you should be able to solve all of these exercises with ease!
