suppose I have 10 pairs of socks for every pair of shoes then the ratio of shoes:socks would be 1:10

✔ 最佳答案
Itis O.K., but NOT expressed clearly. It should be :


(No. of pairs of shoes) : (No. of pairs of socks) = 1 : 10

(No. of pairs of shoes) / (No. of pairs of socks) = 1 / 10

10 x (No. of pairs of shoes) = 1 x (No. of pairs of socks)

正確的表達如以上答案。

圖中內容的錯誤:
把「10 x (No. of pairs of shoes)」錯誤寫成「10 shoe」,
而把「1 x (No. of pairs of socks)」錯誤寫成「1 pair of socks」。

因此才引起你的誤會。

而你有 1 對鞋和 10 對襪,絕不能寫成「1 對鞋 = 10 對襪」!!

若果你有 1000 元紙幣和 1 元硬幣,絕不能寫成「1000 元紙幣 = 1 元硬幣」。
應寫成:
紙幣幣值 : 硬幣幣值 = 1000 : 1
或 1 x 紙幣幣值 = 1000 x 硬幣幣值
