1.係下列個圖裡面,平行四邊形ABCD同ADMN係相似圖形黎既.找出BN既長度.
個圖係咁既...AD,DM,MC,CB,BN,AN同MN係用直線相連的(要幻想下AD,MN同CB三條線都同樣傾斜左 形成ABCD同ADMN兩個平行四邊形)
D M C
A N B
書上面提供既有:AD長度係8(units) AN長度係5(units)
另外我量度過CD真實長度(間尺量度既長度)係岩岩好3.8CM,而BN係2.3CM,AN係1.5CM
2.兩個相同容量既木桶都裝載住麵粉同埋糖.在兩個木桶裡,麵粉同糖既ratio分別係3:1同埋5:1. 麵包師父就將呢兩個木桶裡既所有麵粉同糖倒進一個大容器裡面. 請找出麵粉同糖係呢個大容器裡面既ratio.
英文版:Two buckets of the same capacity are filled with flour and sugar. The ratio of flour to sugar in the two buckets are 3:1 and 5:1 respectively. A baker pours the flour and sugar in the two buckets into one large container. Find the ratio of flour to sugar in the large container.
註:The ratio of flour to sugar in the large container 意思係Flour : Sugar
