An expression is shown. 151/12. between which two consecutive whole numbers does his value lie?

12 and 13 I believe, 151/12 is 12.58, and that is between 12 and 13, which are consecutive numbers, meaning they are numerically in order

Since the original cost is 2700, the fraction 1890 is of 2700 is 1890/2700. Since they both have a 0 at the end, we can cross that out to get 189/270. Next, since their digits add up to factors of 3 (1+8+9=18 and 2+7=9), we can factor 3 out to get 63/90. Repeating the process since these are factors of 3 too, we get 21/30. Doing it yet again since 21 and 30 are factors of 3, we get 7/10 as our answer
