What is the difference between an approximate and an exact number?

An approximate number is a close number that is only off by x number of places (Like a rounded number). An exact number is exactly correct. For example:

3 - 1.5 is approximately 2, but is exactly 1.5.

Mark Brainliest if this helps!

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
