That's why. It's exactly the same thing you're talking about.
- obsurveyor 11y agoYeah, it's the same mental arithmetic. These arguments just don't make sense for making some kind of change.
- sukilot 11y agoNice cherrypick for that pie. And if your car gets 18 or 27 mpg, on a 230 mile trip? Multiplication is generally easier than division.
- maxerickson 11y ago270-30 -> 9 gallons. Real answer, 8.52 gallons. 230 / 20 -> 11.5 gallons. Real answer, 12.2 gallons (and I would know to fudge up). So it is still easy to estimate to within $5.
- perakojotgenije 11y agoBecause it's easier for an average person to multiply than to divide.
