Question 1793: solve 3p/2 - 5p/3=1/5

this starts as a fractions question ten finishes as a simple algebra problem.
Fractions...we need to multiply every term (all 3) by the same number, so that the 2, the 3 and 5 in the denominators all cancel with it, so we get rid of the fractions. That number is the lowest common multiple of 2,3 and 5...namely 30!
so, we get
cancelling, we get , which cancels further to -5p = 6.
Hence p = -
Looking at this, the far simpler solution would be to just combine the 2 fractions on the lefthand side first...

therefore p = -
that is much more elegant a solution :-)
