Last updated at Posted at 2018-11-03

調査

let n = 1000
for i in 1...n {
    for j in 1...n {
        if 1668.0/Double(i) == 2388.0/Double(j) {
            print(i,j)
        }
    }
}

結果

139 199
278 398
417 597
556 796
695 995
2番目からは1番初めのやつの整数倍ですね。

検証

1668 ÷ 139 = 12
2388 ÷ 199 = 12
OKですね。

ざっくりみると

139:199なので、だいたい7:10
7:10に決定した理由ってなんでしょうね。
