5 over 2x5 minus 4 over 5= 1 over 2x5
I have a quick question... what would i multiply by? I know how to do the rest of the problem. Thank you

Lets' start by writing the equation without words.
5/(2x5)  4/5 = 1/(2x5)
Combine the two terms with 2x5 in the denominator.
4/(2x5) = 4/5
20 = 8x 20
8x = 40
x = 5
