In the term percentage, percent means per hundred and this percent can be represented in decimal and in the fractions also.

2、The term ratio refers to the comparison of values between the two numbers which indicate their sizes in relation to each other. In a simple way, the ratio is derived by comparing two qualities by division with the dividend. To find the ratio, we can multiply or divide each term in the ratio by the n

3、umber.百分比转比例练习题，我们可以看看如何将百分比转换为比率。在术语百分比中，百分数是指每百分之一百，这个百分数可以用小数和分数来表示。术语比率是指两个数字之间的值的比较，这两个数字表示它们的大小。一种简单的方法是，用除法和被除数比较两种性质，得出这个比率。为了求出比率，我们可以用比率中的每一项乘以或除以数字。 To convert Percentage into Ratio, we will divide the percentage by 100 to remove the percent % symbol. And we will reduce the given fraction
