The image contains several fraction problems, each requiring arithmetic operations such as addition, subtraction, multiplication, and division. The instructions mention how to handle these operations, such as finding a common denominator for adding or subtracting fractions, converting mixed numbers to improper fractions, and using the KFC (Keep-Flip-Change) method for division.

Here is a breakdown of the problems shown:

### Problem (a): 
\[
21 + \frac{13}{4}
\]
This requires adding a whole number (21) to a fraction. To solve, you would convert 21 to a fraction with a denominator of 4, then add it to \(\frac{13}{4}\).

### Problem (b):
\[
32 - \frac{21}{3}
\]
This requires subtracting a fraction from a whole number. Similarly, you would convert 32 into a fraction with a denominator of 3, and then subtract \(\frac{21}{3}\).

### Problem (c):
\[
22 \times \frac{17}{5}
\]
This is a multiplication problem. You can treat 22 as \(\frac{22}{1}\), then multiply the numerators and denominators across to get the product.

### Problem (d):
\[
21 \div \frac{11}{2}
\]
This is a division problem. Using the KFC rule (Keep-Flip-Change), you would flip \(\frac{11}{2}\) to \(\frac{2}{11}\) and multiply by 21.
