Q: Solve m=xy/n for n
A: OK. Time to get n by itself. Well, we are going to “cross multiply” on this one. Cross multiplying is when you multiply across an equals sign like so:
a/b = c/d
Cross multiply:
ad = bc
The color are there to help you see what multiplies what.
So, we have:
m = xy / n
m/1 = xy/n
Cross multiply
m*n = 1*xy
mn = xy
And, now divide both sides by m (to get n by itself)
n = xy/m
