(1)$$7\dfrac{1}{20} = 7 + \dfrac{1}{20}$$
$$\dfrac{1}{20} = \dfrac{1 \times 5}{20 \times 5} = \dfrac{5}{100} = 0.05$$
$$7 + 0.05 = 7.05$$
The answer is option (1).$$\boxed{7.05}$$

Convert fraction to percentage$$\dfrac{1}{20} = \dfrac{5}{100} = 5\%$$
Convert percentage to decimal$$5\% = 0.05$$
Add whole number$$7 + 0.05 = 7.05$$
$$\boxed{7.05}$$
