See explanation.

#### Explanation:

To calculate Sophie's height we have to do subtraction.

$60 \frac{3}{8} - 6 \frac{1}{4}$

To subtract fractions with different denominators first we have to find the common denominator. Here we can expand $\frac{1}{4}$ to get a fraction with denominator $8$.

$60 \frac{3}{8} - 6 \frac{1}{4} = 60 \frac{3}{8} - 6 \frac{2}{8} = 54 \frac{1}{8}$
