complex fraction的音標是[?kɑ?mpl?ks ?fr?kn]，基本翻譯是“復分數(shù)”。速記技巧是：分母、分子的頭和尾都可以合并，但分子、分母的頭和尾都含有根號時，應(yīng)將根號去掉再合并。

Complex fraction這個詞源自拉丁語“complexus”，意為“復雜的”。它的變化形式包括復數(shù)形式“complex fractions”和過去分詞形式“complex fractions”。

相關(guān)單詞：

1. Complex number（復數(shù)）：表示有兩個或更多不同實部的數(shù)的數(shù)學概念，源自complex fraction。

2. Fractional（分數(shù)）：表示部分與整體之間的比例，源自complex fraction。

3. Fraction（分數(shù)）：表示部分與整體之間的數(shù)字比例，是fractional的縮寫形式。

4. Quadrant（象限）：在直角坐標系中，將平面分為四個象限的圖形，源自complex fraction。

5. Division（除法）：在數(shù)學中，將一個數(shù)分成幾個部分的過程，源自complex fraction的分解。

Complex fraction在英語中不僅用于表示復雜的分數(shù)，還用于表示復數(shù)形式的分數(shù)，它在數(shù)學和物理學中都有廣泛的應(yīng)用。Complex fraction的出現(xiàn)使得數(shù)學更加豐富和復雜化，也為科學和工程領(lǐng)域提供了更多的工具和概念。

Simplifying Fractions: The Basics of Math

In mathematics, fractions are a fundamental concept that we use to represent parts of numbers. Simple fractions are easy to understand, but when we encounter complex fractions, the process of simplification becomes tricky. However, with practice and understanding of the basics, we can master this skill and use it effectively in our daily lives and in our academic pursuits.

When dealing with complex fractions, we need to identify the parts that make up the fraction and simplify them individually before combining them again to get the final result. This process can be tedious and time-consuming, but with patience and practice, we can overcome any challenge that comes our way.

In conclusion, fractions are an essential part of mathematics and mastering the art of simplifying them is key to success in this field. With practice and patience, we can overcome any obstacle that stands in our way and achieve our academic goals.
