Question 68527
x/5=20/4
----------
You want to isolate the "x" on one side of the equal sign.
The "5" is in the way and it is in the denominator.
Multiply both sides by 5; that way you will cancel the 5 in the denominator.
5(x/5) = 5(20/4)
The 5's cancel on the left of the equal sign.
The common factor of 4 cancels on the right of the equal sign.
----------
You are left with:
x=5*5
x=25

Hope this helps.
