1. 題目是錯的,估計正確題目為
568 / ? = 23....16
解題
568-16= 23 x ?
552 / 23 = ?
? = 24

2. 又可能係錯
81 x 31 = 39 x ?
2511 = 39 x ?
2511/39=?
?=64.384615

要出現整數最有可能係 93, 即
81 x 31 = 93 x ?
2511 = 93 x ?
? = 2511 / 93
? = 27

請問係邊本作業咁恐怖

It's the homework exercise. I wonder if they want the answer in fraction. But would it be too
complicated for P4?

4年級方程式來說不算太深,但題目錯了玩死9成幾人度啦.
