Equation 1: 21 equals 100%
Equation 2: 'x' equals 5%

Step 6: To solve for 'x', we divide equation 1 by equation 2, considering that both equations have the same unit (%). Thus, we obtain:
21 / x = 100% / 5%

Step 7: By taking the reciprocal of both sides of the equation obtained in Step 6, we have:
x / 21 = 5 / 100
⇒ x = 1.05
