Percentage of 28 out of 31 = 28/31 * 100% = 90.32%
9 x 27 + 2 x 31 - 28..... Multiplication sums are first so... 9 x 27 = 243 & 2 x 31 = 62.This gives the new sum of 243 + 62 - 28. Addition is next... 243 + 62 = 305.Finally... 305 - 28 = 277

Since 28 is smaller than 31, and 28 represents a part of 31, logically your answer should be less than 100%. I was always taught to translate the English words of a problem like this into the language of math in this way: What percent (x/100) of (times) 31 is (equals) 28? Then the equation to solve would be: x/100 • 31 = 28. Solving for the unknown, x, which represents a percentage, the answer is 90.32%, rounded to the nearest hundredth.

The median of 31 28 30 31 30 is 30.
31 + 24 + 28 + 33 + 28 + 27 + 25 = 196/7 = 28
Put them in order as 28 30 30 31 31 and the median is the number in the middle, which is 30.
4! + (4 + 4!)/4 = 24 + (4 + 24)/4 = 24 + 28/4 = 24 + 7 = 31
