Hello!
You have to subtract 7 1/4 and 2 1/2. First change both to a common denominator to make it easier.
Common denominator: 4
[tex] 2 \frac{1}{2} = 2 \frac{2}{4} [/tex]
[tex] 7\frac{1}{4} = 7\frac{1}{4} [/tex]
[tex]7 \frac{1}{4} - 2 \frac{2}{4} = 6\frac{5}{4} - 2 \frac{2}{4} = 4 \frac{3}{4} [/tex]
Answer ⇒ [tex]4 \frac{3}{4} [/tex]
