Question

describe a real life representation of the following 12/140 = 0.09

Answer 1

Only 12 out of 140 people aced the test. Miranda wanted to know the percentage of people who aced the test, so she divided 12/240, which equaled .09, or 9% of students.

Answer 2

A horrible math student took a test worth 140 points.  When the test came back the student only get 12 points right.  His grade was a 9%.

12/140 = .085 which rounds to .09.  Multiply by 100 to get 9%
