How to get a radical out of the denominator?

You can get the radical out of the denominator by multiplying the radical on the top AND the bottom so it's like x/x=1 so you're not changing the equation. By multiplying the same radical on the top and bottom you can get the radical on the top only!

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
