100 Days Challenge. 7/100 If there are any grammar mistakes and/ or weird word choice, please correct them. Thanks It makes me confusing. In case of thinking a number of percentage, there are something I have to be careful. When I consider some number such as survey or statistics, I often use a fraction. But if the numerator is smaller the better when it is compered between before and after, the denominator has to be the same number. In addition, a condition, a method and quantity are has to be the same every time, otherwise it doesn’t make sense at all. If the number of denominator is modified intentionally, the result might be able to be different.
