Explanation:

Step1: Divide numerator by denominator

To convert a fraction to a decimal, divide the numerator by the denominator. For $\frac{3}{16}$, we calculate $3\div16$. $$3\div16 = 0.1875$$

Step2: Convert decimal to fraction

To convert a decimal to a fraction, we use the place - value of the decimal. For $0.375$, since $0.375=\frac{375}{1000}$, and then simplify by dividing both numerator and denominator by their greatest common divisor (GCD). The GCD of 375 and 1000 is 125. $$\frac{375\div125}{1000\div125}=\frac{3}{8}$$

Step3: Already in fraction form

The fraction $\frac{7}{8}$ is already in fraction form.

Step4: Convert decimal to fraction

For $0.625$, we have $0.625=\frac{625}{1000}$. The GCD of 625 and 1000 is 125. $$\frac{625\div125}{1000\div125}=\frac{5}{8}$$

Step5: Convert decimal to fraction

For $0.875$, we have $0.875=\frac{875}{1000}$. The GCD of 875 and 1000 is 125. $$\frac{875\div125}{1000\div125}=\frac{7}{8}$$

Answer:

21. $0.1875$
22. $\frac{3}{8}$
23. $\frac{7}{8}$
24. $\frac{5}{8}$
25. $\frac{7}{8}$
