Hey!
Let's change Nicholas's height to inches so that you can compare both heights.
1 ft = 12 inches
4 ft = 12 × 4 = 48 inches
48 + 4 = 52
Annabelle is 53 inches tall, and Nicholas is 52 inches tall. Subtract to find the difference.
![53 - 52 = 1](https://img.qammunity.org/2019/formulas/mathematics/middle-school/nzcw5glj5sstxv55ceq4fv8ryuf9j2sh52.png)
That means Annabelle is 1 inch taller
