Question

125 centimeters to 87.5 centimeters

Answer 1

In this question we need to find the percentage of change, that is, we need to compare old to new values. So, in this problem we have that:

125 centimeters to 87.5 centimeters

is a decrease of 37.5 (that is, 125-87.5) centimeters, that is the change ( we have subtracted old value from the new value). So, the percentage of change is obtained by dividing that change by the old value and multiplying by 100, then:

$\frac{37.5}{125} \times 100 = \boxed{30 \%}$
