You can put this solution on YOUR website!
Okay, let's say you had $50 and you needed to divide it out to 5 different people. How much would each person get? In this case, you are looking for dollars per person. (per means divided by)
Dollars%2FPerson
The way you can show that with math is to say that $50/5 people=$10 per person. In this case you started with $50 and divided it out to 5 people.
WhatYouStartWith%2FWhatItsDividedOutTo
So it doesn't matter what you're looking at, you can just use the "per" as a dividing symbol for whatever you're looking to calculate.
Elephants per circus = Elephants%2FCircus
Circuses per elephant = Circuses%2Felephants
Tickets per stadium = Tickets%2FStadium
Beats per minute = Beats%2FMinute
Random Words said per minute of me talking = RandomWordsSaid%2FMinutesOfMeTalking
A per B = A%2FB
The same holds true with your two questions.
Your first question is asking, how many dollars paid per pound of flour? We know what to do here:
Dollars%2FPoundOfFlour = 5%2F12
The 2nd question is asking pounds of seed per acre. Hopefully you're comfortable with this by now, and know to just put the "per ___" on the bottom. That gives you:
PoundsOfSeed%2FAcre = 45%2F5
