X = what
2/X = 5
multiply through by X ( X/1 for illustrative purposes )
X/1(2/X = 5)
as you see the X's cancel each other, top an bottom, in the X/1 and 2/X terms, then the X multiplies the 5
2 = 5X
divide both sides integers by 5
2/5 = (5/5)X
2/5 = X
========check in original equation
2 divided by 2/5 is the same as 2 * 5/2
2 * 5/2 = 5
5 = 5

(5 divided by 5) + (5 divided by 5) = 2
8 divided by 2 equals 4. and 16 can be divided by 4 to equal 4 for 8/2 to equal 2/8
2/3 divided by 5 become 2/3 multiply 1/5 which is equal to 2/15
5 over 2 (or 5 divided by 2) equals 2 and 1/2
