When geologists want to study an active earthquake fault, they often rely on a trenching study. ... They brace the walls, if needed, to prevent cave-ins, then they climb down into the trench and carefully map its walls, looking for signs of past earthquakes and ground movement.
The given information is expressed in ratio. However, a ratio is basically a fraction. So, 4:10 is just equal to 4/10 or 2/5 in simplified terms. Similarly, 12:20 is just equal to 12/20 or 6/5 in simplified terms. The smaller ratio is 2/5 because the numerator is less than the denominator. So, it follows that the answer is less than 1. The other ratio has a much greater numerator. So, we would expect that that would be greater than 1.
