It's time to downgrade my big fish tank. I only have two of the original ten fish left. They died of old old age, by the way. So I got out the little fish tank I use for transportation.
It had been about five years since I last used it, so I didn't exactly remember how many gallons it held. I estimated that it would take about three gallons to fill. I even put it beside my Keurig, which takes about a gallon, for reference.
So, off to the cupboard I went to get the gallons of water usually kept in there, but my hubby apparently didn't tell me we were down to one gallon. Oh, well. I poured it in to see how much it would fill before running to the store.
One gallon filled the tank almost halfway.
So, I needed to revise my original estimate of it being a three-gallon tank. It would only take about another gallon to almost completely fill it, which is a total of two gallons. Still, the scientist in me was screaming, "Buy two more gallons, just in case!". It's better to be over-prepared than unprepared.
Turns out, 2 gallons did the trick.
So, with a little estimation and trial-and-error, I got my math on. It's true, Math is Real Life! If you want to join the link-up and share your real-life math experiences, click here.
